There are a whole lot of related factors at play when it comes to choosing wisely. Not all these would apply to all exotic pets; in general, the "wilder" the animal you choose, the more careful you should be.
- Source - will you go to a pet store, breeder, or shelter? Depending on the pet you get, your choices may be limited, but there are some pros and cons of different sources of pets covered in "Where to Get a Pet."
- Captive Bred is Best - for the wilder set, this is really the best option. A captive bred animal is likely to be less stressed, and therefore healthier, and also much easier to handle. They are also more likely to feed well (especially important for snakes). Not only that, you won't be contributing to the problem of declining wild populations due to capture for the pet trade.
- Shelters Aren't Just for Dogs and Cats - you might be surprised at the variety of critters available from shelters and rescues. If possible, please give a shelter animal a second (or third, etc.) chance at a happy life.
- Pick a Healthy Pet - if you look around a bit at some different animals, you will get a sense of what a healthy pet looks like. Check for things like bright eyes free of discharge, alert expression, quiet breathing, healthy-looking skin and coat, good body condition, and no evidence of nasal discharge or diarrhea.
