This strain on the kidneys can be worsened if the iguana is put on systemic antibiotics, so all antibiotic therapy should be accompanied by fluid therapy to ensure the iguana is getting sufficient fluids for his normal daily needs as well as additional fluid to compensate for the effect of the drug on his kidneys. Mites are visible to the naked eye but are hard to see in small numbers. When expressing fluids or liquid nutrition slurries into a reptile, do it slowly enough so that it flows down towards the stomach, rather than so fast that it backs up into the mouth. When dealing with venomous reptiles, matters are rather compounded by the fact that you may get more than a few teeth left behind in a bite wound. Pathogenic trematodes infect the vascular system of turtles and infect the oral cavity, respiratory system, renal tubules, and ureters of snakes. Numerous snakes are infected by Kalicephalus spp.

The mere act of being alive requires a certain amount of energy calories and fluid intake on a daily basis or aggregate basis, in the case of those species that, as a normal course in healthy members of the species, eat less often than once a day. If, in addition to just sustaining the minimum body functions, the body must also grow, engage in reproduction, experience stress, recover from injury, etc. With reptiles, the fluid requirement issue becomes a bit more complicated as reptile species are found in such a wide range of habitats and live a variety of life-styles.
Each species has adapted to its environment over millions of years. Eventually, the populations were composed of those individuals whose ancestors best adapted to the changes. Adapting to life in captivity cannot be compared to the thousands or millions of generations required for a wild organism to adapt to a changing environment. Captivity, even under the best of circumstances, rarely duplicates everything the organism would be subjected to in the wild, including the variables found in water constituents, nutritional and other variables in food animals or plants, amount ultraviolet radiation, microclimates, etc.
Many species may appear to adapt quite well and go along for years, portraying the very picture of health and well-being, only to be felled at a relatively early age to organ failure due to something related to the captive environment, or fails to rally after an apparent minor stressor. Stress itself is a factor in behavior, health, illness, and recovery. Since captive animals, even apparently well-adjusted ones, are living in a condition of chronic stress, routine captive care practices must include mediations to help overcome or compensate for the long term effects of stress.
What kinds of stressors can lead to dehydration? Providing the basic daily fluids may be as simple as installing a bowl or pan of water that your reptile can easily drink from or soak in. For large reptiles, this requires both a suitably large enclosure in which to house the large reptile and its large tub of water and still leave plenty of room for him to move around, thermoregulate, etc. Drip systems, which may be a primitive as a homemade drip bottle or an expensive green house mister, will be needed for species native to humid climates.
For other species, an area of substrate will need to be kept damp, or a humidity retreat box provided some or all of the time. These suggestions and more can be found in my article on Microclimates. A Note On Heating vs. Someone once wrote to me stating that they were keeping their reptile's room and enclosure cool so as not to dehydrate them.
While this person's desire to prevent dehydration is good, the way they were going about it - by depriving the reptile of the temperatures it needed for its body to function properly, was just as ultimately deadly as heating it properly without regard to hydration.
Reptiles are complicated animals, with species-specific thermal requirements that must be met for the animal to not only subsist, but thrive. You cannot sacrifice one environmental for the other, but must provide them to ensure overall health and functioning. Green iguanas - a particularly problematic species Green iguanas Iguana iguana are complex lizards whose captive requirements drive many iguana keepers running, babbling, and blithering for their own basking spot.
Enclosures made of suitable mesh products are great for providing adequate ventilation, but they are almost impossible to keep heated properly without heating the entire room.
Thus, green iguanas tend to be rather high maintenance lizards as keepers struggle to provide the humidity needed to fend off early kidney failure while keeping them warm enough to enable proper systemic functioning. Sufficient fluids are particularly critical when the iguana has suffered a thermal burn, is gravid, or is on systemic antibiotics for an infection or fighting a mild infection without antibiotics.
Ways to increase iguana and other wet, rain, and cloud forest species' humidity and fluid intake include: Fluid Requirements Generally speaking, the daily fluid intake for reptiles is. Certain injectible solutions used for rehydration and provided by your veterinarian have specific quantities, determined anecdotally or pharmacokinetically: The solute of choice is: Fluids can be administered subcutaneously, intracoelomically, intravenously, or intraosseously. Do not administer intracoeloemically if there is a suspected space-occupying lesion, pneumonia, obstipation, egg retention, or preovulatory follicles.
Divided Doses The daily amount of fluid cannot be administered all at once; instead, it should be divided into doses. This prevents overloading the kidneys. Under normal circumstances, healthy animals who are eating and drinking normally and who are living in an environment that meets their humidity needs will succeed in keeping hydrated. The factors described above can lead to dehydration, especially in wounded or starved animals.
Green iguanas and others species who evolved in high-humidity environments may experience a chronic low level of dehydration throughout their captive lives that ultimately cause kidney damage and an early death due to kidney failure. This strain on the kidneys can be worsened if the iguana is put on systemic antibiotics, so all antibiotic therapy should be accompanied by fluid therapy to ensure the iguana is getting sufficient fluids for his normal daily needs as well as additional fluid to compensate for the effect of the drug on his kidneys.
If your vet prescribes oral or injectible antibiotics for your iguana, be sure to ask about supplemental fluids PO, IC or SQ during the time the iguana is taking the antibiotics.
Routes of Administration There are various ways that fluids can given to a sick reptile or one requiring additional fluids for a specific reason, such as in conjunction with systemic antibiotic therapy, or to correct moderate to severe dehydration.
Reptiles who have been starved to the point of emaciation will require rehydration before nutritional support can be started. The following routes of administration are for these exceptional needs, not for administering basic maintenance fluids on a daily basis to an otherwise healthy reptile.
In mammals, fluids are generally given by IV as it is the most direct and efficient way to get the fluids into and circulated throughout the body. Unfortunately, this is tricky at best when it comes to reptiles, as anyone who has ever tried to draw blood from a major blood vein in a reptile knows.
Since fluids are most often administered at home by the reptile keeper, most of whom do not have experience hitting a vein intentionally and repeatedly in their reptiles, there are other ways that are easier, though it may cause the reptile keeper more stress than it does their reptile.
You must observe how your cat attacks bones, and take note of her next couple of bowel movements to see whether she is eating the actual bone. If the stools are bloody, if there is any indigestion, discomfort, gas, vomiting, bloating or if there are any shards of bone in the stool, then discontinue feeding whole bones. If your cat is constipated, then you may need to reduce the amount of bone you are feeding. Doing so can cause the bones to splinter, making them sharp with the possibility of puncturing the intestinal system.
When you feed a cat bone-in cuts of meat, such as chicken wings or necks, the cat has to use their side teeth to chew and cut the meat into pieces small enough to swallow. This vigorous use of the side teeth helps to keep the teeth clean, the gums stimulated and the jaws exercised.
This is not only beneficial to their dental health, but helps to keep them mentally stimulated. Calcium is the most abundant mineral in the body. By the time you see symptoms of a calcium deficiency, your cat has often been calcium deficient for months or years.
That is why it is so important that everyone who has their kitten on a raw food program be sure their animal is getting sufficient level of this important nutrient. Most of the calcium in the body is utilized by the bones and teeth. However, it is also involved in the blood-clotting process, in nerve and muscle stimulation, parathyroid hormone functions and the metabolism of vitamin D.
To function properly along with the high phosphorus content in meat, calcium must be accompanied by magnesium, boron, copper, molybdenum, potassium, sulphur, zinc and vitamins A, B6, D and E. The clavicles collarbones are either reduced or absent entirely and, if present, are usually embedded in muscles without articulation with other bones. This allows for a greater flexibility in the shoulder area and prevents breakage of the clavicles when the animal springs on its prey.
The brain is large in relation to the weight of the body, and it contains complex convolutions characteristic of highly intelligent animals. The stomach is simple as opposed to multichambered, and a blind pouch cecum attached to the intestine is usually reduced or absent. The teats are located on the abdomen along two primitive lines milk ridges , a characteristic of mammals that lie down when nursing.
Many carnivores have a well-developed penis bone, or baculum. It appears that this structure plays a role in helping to increase the success of copulation and fertilization of eggs in species where numerous males mate with a single female.
Cats have a vestigial baculum or none at all, but the baculum of the walrus can measure up to 54 cm 21 inches. Carnivores are found worldwide, although Australia has no native terrestrial members except for the dingo , which was introduced by aboriginal man.
Terrestrial forms are naturally absent from most oceanic islands , though the coastlines are usually visited by seals. However, people have taken their pets, as well as a number of wild species, to most islands. For example, a large population of red foxes now inhabits Australia, having been introduced there by foxhunters. Introduction of carnivores to new environments has at times devastated native fauna.
In New Zealand , stoats, ferret s and weasel s were introduced to control rabbits, which had also been introduced. As a result, native bird populations were decimated by the carnivores. Birds were also a casualty of mongoose s introduced to Hawaii and Fiji, where populations of introduced rodents and snakes had to be controlled. In Europe, American mink s released from fur farms contributed to the decline of the native European mink. Because carnivores are large and depend on meat, there must be fewer carnivores in the environment than the prey animals they feed upon.
In general, carnivores have a population density of approximately 1 per 2. By comparison, omnivorous mammals average about 8 per square km 20 per square mile , and herbivorous rodents attain densities of up to 40, per square km , per square mile at peak population. Relatively low population density makes carnivores vulnerable to fluctuations of prey density, habitat disturbance, infectious disease , and predation by man.
The mobility and adaptability of some carnivores has enabled them to shift ecological roles and survive changes brought about by human activities.
For example, the red fox, coyote , raccoon, and striped skunk can all be found in urban and suburban areas of North America. In Europe, the red fox lives in most large cities. Most other species do not fare nearly as well. The gray, or timber, wolf and brown bear once lived across much of the Northern Hemisphere, but their ranges have shrunk following habitat destruction, reduction of prey abundance, and persecution as competitors with man. In Africa and southern Asia the same can be said for lions and tigers.
Numerous cats and bears and some seals have become rare and are threatened with extinction. There is great diversity in Carnivora, especially among the highly specialized pinnipeds. Thus, the characteristics used to separate Carnivora from other mammalian orders and to define the subdivisions of Carnivora are primarily structural.
Of great importance are certain features of the skull such as jaw articulation , feet number of toes, lack of opposability of the hind toe, type of claws, and fusion of certain bones , and teeth both the overall tooth pattern and the shape of individual teeth.
Dentition is especially important in determining the relationships of fossil forms. Also useful in the taxonomy of modern carnivores are the convolutions around the lateral, or Sylvian, fissure of the brain, the relative weights of the adrenal and thyroid glands, the type of uterus and placenta, and the position of the nipples. The taxonomy of the major categories of major groups placed in the Carnivora has been in a state of flux for more than a century, and these categories do not seem to be stabilizing, even today.
Most mammalogists at present regard the seals and terrestrial carnivores as belonging to different orders, the Pinnipedia and Carnivora. There are, in reality, only a few features common to the seals and their terrestrial relatives because of the extensive and numerous adaptations the aquatic forms have undergone to make them efficient carnivores of the sea.
Mammalogists who have studied seals intensively now realize that there is no anatomical structure unmodified by the extensive aquatic adaptations; every organ and tissue examined has been found to be different in some way from its counterpart in terrestrial forms. This more conservative taxonomy is followed in this article. Of the living families recognized in the Carnivora, two have separated from their lines most recently and are most easily associated with other existing families: Moreover, a new family, the Mephitidae skunks and stink badgers , has been proposed as an offshoot from the Mustelidae weasels.
It appears that skunks do indeed possess enough differentiation in features and genetics to warrant the new grouping. Taxonomy of several species of carnivore remains uncertain. Among those, two of the most problematic species are the lesser, or red, panda Ailurus fulgens and the giant panda Ailuropoda melanoleuca.
Both species have been classified equally often in the Ursidae bears or the Procyonidae raccoons. However, the latest classification places the giant panda in Ursidae and the lesser panda in Ailuridae.
Another lesser-known species, the fossa Cryptoprocta ferox , is regarded as a viverrid but retains characteristics of cats as well.
It has been alternatively placed in Herpestidae, Viverridae, and even Felidae. The arrangement of the nine terrestrial families into two distinct superfamilies, Canoidea and Feloidea or Aeluroidea , appears to be a natural arrangement dating back to the works of W.
Winge in the late s. In Canoidea, as revealed by studies in comparative anatomy and the fossil record , the families Canidae, Ursidae, and Procyonidae seem to be most closely related. Also placed in the Canoidea is the family Mustelidae, although some of the more primitive members show resemblances to the primitive viverrids as well as to the canids.
In the Feloidea, the families Viverridae and Hyaenidae seem most closely related, the Felidae being the most aberrant. Those families that contain rather diverse lines have been divided into subfamilies, the number of subfamilies in each family indicating the amount of evolutionary divergence that has occurred. The groups that have probably been distinct the greatest length of time have the most subfamilies, Viverridae with six and Mustelidae with five.
As a result of such complicated taxonomic appraisal, the formal classification of Carnivora is in some ways an artificial system set up for the sake of convenience.
Ideally, the system reflects real evolutionary relationships, but these must be inferred from a scanty fossil record and from comparisons of modern species.
