We brought a re-homed cat home to our house one week ago. She is 4 years old, spayed, up to date on shots and healthy. She came from a multi-cat and dog house to our single-dog house. Her previous owner says she had no problem standing up for herself against other cats and the dog (reports the other cats are much more willing to come out of hiding since she has been removed). We have noticed that she is shy and skittish, but eating and drinking. She spends most of her day hiding under a bed.
Unfortunately she refuses to use her litter box (so far preferring kids closets and under desks). We’ve taken a step back and confined her to a single room. She has a clean litter box. Food, toys and bed are at the opposite side of the room. We’ve also confined the dog to a separate part of the house
None of this is ideal. We have few doors, so keeping them apart also keeps the humans apart. I can put food or litter in another part of the house, but the cat is more likely to encounter the dog if I do that.
