From a person who's had up to 10 kitties (now, gratefully down to 4 - MUCH better for my situation, although it was really great to be able to give needy kitties a home! ) I strongly advocate having another kitty for a playmate for your initial, demanding kitty.

My first cat was Noah, the fluffy, orange kitty in my avitar. When he was a baby, he was just like your kitty and worse, he thought I was his playmate. I remember sitting down to dinner and having him CRAWL up my legs (wearing shorts) and bursting into tears because A: it hurt and B: he thought of me as his play toy, not his mommy. As SOON as we got our 2nd cat, things changed completely! I became mommy and Noel (2nd cat, who was approx 4 months old then) became his buddy!

Lots of luck!! Do you have any pictures of your kitty you can show us? We ADORE pictures, especially KITTEN pictures!
