My cat just started to sit quietly in her clean litter box yesterday. Today she started to roll around in her clean litter box happily. I can't understand what's going on?

Tippy, if your cat doesn't seem ill and is happy, it just might be that she is letting everyone know that the litterbox is hers. If you are concerned that something is wrong, please make an appointment with her vet for an exam.

She is enjoying her "clean" litterbox. One of my cats enjoys sleeping in her "clean" litter box.

We are thinking of adopting a small young puppy dog and wondering how our 4 year old cat may react. Any advice on thpes of dogs and techniques to introduce them is most welcome.
