In most cases, it’s fine if you already have a cat and/or dog, as long as your pet and the foster pet are both healthy and well behaved around other animals. If you foster kittens they will need to be kept in a separate room away from your other pets. Prior to arranging any foster home, an introduction will be done between your current animals and the animal we need to have fostered in order to ensure it will be a fit for the whole family.
