Consider housing. Cats and dogs can roam freely, but fish and exotic pets require housing that looks and feels like their natural habitat. While some exotic pets, like ferrets, can roam free in your house like cats and dogs, others cannot. For example, reptiles carry diseases that are dangerous for humans, so they should be kept properly caged.
If you have to purchase a cage or tank, think about how large your pet will grow and purchase a home that will meet his needs long-term. If you adopt more than one of the same animal, they may require a larger home to share or separate homes depending on the species.
Turtles and amphibians may need tanks that have both water and “land” to be completely fulfilled. Since reptiles are cold-blooded, you may have to invest in a UV light to help regulate body temperature.
Veterinary costs. Cats and dogs require regular examinations and vaccinations, and so do many exotic pets. All pets have specific needs, so don’t assume that small pets like fish are easier to care for. Do your research and find a veterinarian who specializes in the care of your particular pet.
If you already have pets, talk to your veterinarian before adopting another one. Your vet can help you navigate local laws for exotic pets and ensure all your animals are compatible and will get along. They can also give you tips for introducing your new pet to the ones you already own.
Food. Pet food nutrition labels aren’t the same as those for human food but as with humans, quality is better. Cats are meat eaters and need diets that are high in animal protein. Your dog must have water, protein, fat, carbs, and some vitamins and minerals to be healthy. Other animals, like snakes, are carnivores and need to eat thawed, pre-killed rodents to meet their nutritional needs.
Some reptiles require a variety of fresh vegetation. You may be tempted to just give lettuce, but your pet will not get enough nutrients to thrive without variety. No pets should be given human food unless it is cooked meat or fresh fruits and vegetables that are safe for your particular breed. Processed foods are highly dangerous to many species. Fresh water is an important requirement no matter what kind of pet you adopt. Always check with your vet for advice on what is best for your pet's nutritional needs.
