A refuge is a less-traveled or out-of-the-way area of the home where the cat has access to all the necessities; food, water, a litter box, a scratching post, perch, and toys. This should be a place where your cat feels safe and comfortable, for example a bedroom or back room.
The refuge is a place your cat can retreat to when she needs quiet time alone. Your cat should be able to come and go freely from her refuge. When the cat is in her refuge, other members of the household, including people and pets, should not be allowed to bother her.
Leaving a radio or TV on for your cat muffles sounds she hears but can't identify. The radio or TV will also provide human voices for your cat to associate with safety. Using Feliway spray or a Feliway Diffuser in your cat's refuge can make it seem safer and more inviting.
