Over the holiday weekend (Saturday) one of my cats, Phoebe, had to go in for emergency surgery. She had pyometra (infection in her uterus). She is much better now, only stayed overnight. But since she has been back, one of my other cats, and her best friend, Jade, acts like she doesn't know her. Jade and Phoebe use to be best friends. In fact, Phebs 'adopted' Jade when she first came to live with us. We got Jade when she was only four weeks old. Now Jade hisses at her and runs. Here is a photo of what they use to be like together. Cats drive me crazy!
