Animals are not toys. They require love and attention and a lifetime of proper care, and it is unfair to both the animal and the gift recipient if that responsibility is suddenly imposed on them.  If you have already discussed the idea with the prospective recipient at length, and you know that they have the time, willingness, ability, and resources to properly care for an animal and make such a serious commitment, you should consider giving them a gift certificate from the local animal shelter and going with them to adopt their new companion.

It is always best for the potential new pet owner to choose their companion themselves.
