{{Big Hugs}} to you. I had to do the same thing for my 8 yr old grey tabby kitty Mikki(in Jan) whom I raised from age 3 weeks up(she was an orphan). I also lost my 7 week old kittens to an accident 2 weeks ago and my daughters grey kitten Smokey got ran over. So I know how you feel. It's hard when we lose our favorite furry friends. I'm quite attached to all my kitties.
