I have a little girl kitty that looks a lot like your boy. I've got a very soft spot in my heart for black kitties now. My baby and I are coping with renal failure. I'm giving her sub-cutaneous fluids at home three times a week. Seems like a lot of trouble, but after being very sedate she is playing like a kitten again. I will keep her going as long as I can and as long as she is not is pain. She will be 5 wext week, so it's not an "old age" issue.
