My cat has always liked sleeping in that tiny box in the bike closet, but sleeping for two days isn't normal, not even for her. I took her to the vet where she was diagnosed with kidney failure. I got her a year and a half ago, she was old and abused and hated everybody. She still hates everybody. Not me. Anymore. She stopped biting me last summer and we've become friends. I'd like to keep this friend for a while longer but I know she's old. Time will show.
