Those critters and other exotic species make up about 9 percent of the American pet population, an American Pet Product Manufacturers Association survey says.

But do they really make good pets?

Before taking on an unusual pet, be sure to read up on its environmental and care needs. When such pets develop veterinary or behavioral problems, says Tampa veterinarian Teresa Lightfoot, it usually has something to do with their care.

``It's important for caretakers to be very knowledgeable about the animals native environment and attempt to mimic that in captivity,'' says Lightfoot, who is board certified in avian species. She also sees a variety of exotic species at Florida Veterinary Specialists in Tampa.

Some exotics become ``fad pets'' that are popular for 10 to 15 years. Recent examples include potbellied pigs, sugar gliders, prairie dogs and hedgehogs. Not all of the more popular exotics make good companions in captivity.

Take sugar gliders. These tiny flying squirrel-like animals are adorable, but they're nocturnal. They're up all night - and they can make quite a ruckus. Sugar gliders weigh 2 to 3 ounces as adults, but their enclosure should be a minimum of 8 feet tall to give them room to leap or ``fly.''

``The gliders' natural diet is difficult to mimic because they eat nonnative insects and nectar from plants,'' Lightfoot says.

And they can't be trained to use a litter box.

Other fad pets to be cautious of include hedgehogs and prairie dogs. The African hedgehog is difficult to handle and becomes more reclusive with age. The prairie dog, raised in captivity, often develops behavior problems, obesity and difficulty with the roots of their teeth due to caged enclosures.

Some exotics, however, can become good pets if caretakers understand their needs.

``Captive-bred skunks can make cool pets because they have catlike personalities, they are litter-box trainable and, when bred in captivity, there is little to no rabies concern,'' Lightfoot says.

Ferrets make good pets because they're playful and enjoy the company of humans. They can also be litter trained and can be taught to come to cues such as bells or whistles.

Where reptiles are concerned, the bearded dragon may be a better pet lizard choice than the popular iguana. The dragon is smaller and docile. Iguanas can reach a length of 5 to 6 feet. As they approach maturity, they may begin to demonstrate seasonal aggression. Both genders can become quite dangerous during this time, with biting, tail lashing and scratching.

Study First

Whether reptiles, birds or mammals, both pets and people benefit when caretakers know what they're getting into. Here are some ways to study up.

Needs: Learn about the animal's needs, getting information from a variety of sources. ``The ideal situation is to find a good breeder and a veterinarian with an exotic pet practice that work together,'' Lightfoot says.

Reputable breeders discuss how to handle the animal and what behaviors to expect. Veterinarians with a practice focused on exotic pets can educate you about the routine veterinary care necessary. As a supplement, look into local or online clubs for exotic pet owners.

Environment: Know how to provide an appropriate enclosure. What substrate or flooring is needed? Are there special lighting, humidity or temperature requirements?

Nutrition: Captive nutrition is formulated for specific exotic pets and is available commercially. However, when possible, strive to provide natural nutrition by finding the plants, herbs or insects your exotic pet would eat in the wild.

Activity: Animals may have special habits such as preening, grooming or foraging. Learn which to expect and how to provide stimulation or an environment that facilitates those behaviors.

Veterinary care: Some primary care veterinarians do well with basic care for exotic pets. It may be best to seek out a veterinarian that specializes in your species.

You can make some of those contacts this weekend at the Florida International Reptile and Exotic Animal Show. It runs from 9 a.m. to 5 p.m. today and Sunday at the Florida State Fairgrounds. More than 250 exhibitors will have species experts, breeders and manufacturers. Tickets are $8 for one day or $14 for both.
