Know what they are and then make your decision to purchase. Any animal, domestic or exotic, demands a high level of owner responsibility. Becoming bored with a pet is NOT an option, especially when it comes to exotic pets, You can't just find another family for your 5 foot Iguana, your over grown Siberian Lynx or unwanted snake. Please, for the sake of the animal, be committed to the long haul. Realize you have a responsibility to the animal, the exotic pet industry, the general public and your own dignity.
Exotic pets are very time consuming.
Depending on the pet it could take hours every day to train, discipline and care for your exotic pet. Just the domestication process alone can be very taxing in time and patience. Most people acquire a pet for one of several reasons. They want it for companionship, for the novelty or for sheer enjoyment. These pets are exotic primarily because they come out of the wild and are not naturally tame or social with people.
