This is my boy:



Lovely critter.
But please, please, for the sake of this fine feline go to the feline diabetes site and read the research about dry cat food and why canned food is better.
I loathe canned cat food. It is inconvenient, and my cats wake me at 5 AM wanting to be fed. But while I switched for the sake of Pye the diabetic, the other two, including Wilbur who in addition to swallowing thread also plugged solid 9 years ago, are also benefitting.
My family has two. The one shown below is Tommy, our youngest (now 8).

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.
