Give your cat or dog time to become accustomed to its new home.
If your pet hides in a particular room… read or watch TV quietly there so it gets used to your normal activities.
If your pet has bathroom accidents… it could be sick, so see a vet. Or maybe your cat just dislikes its litter box or your dog feels scared. Visit the Humane Society of the United States’ pet care Web site, petsforlife.org, for tips on solving these problems.
If your pet fights with other pets… feed it near those animals so it associates them with something pleasant. If your pet bites you… find a trainer from the Animal Behavior College at animalbehaviorcollege.com.
