We think Mishi is a little over 2 years old, but he's still very kitten-like; albeit a HUGE 16 lb. "kitten" He has grown since I got him so I suspect he was probably younger than they thought. I think (hope?) he's done growing - my apartment is not that big, although I love having the huge dude cavorting around - it keeps me entertained!

Enjoy their kitten-ness while it lasts. My Goldie was very kitten-like until she hit somewhere around 10-12 years old.
