Wowsers! That sounds expensive!

I've don't take my kitties for their annual. I've never really thought about it because one of the vets at my place is my brother's friend. He doesn't come over much, but he sees my pets often enough. He always lectures me about their weight (Ron especially). But now that I'm hearing you all talk about blood work and stuff, maybe I should! Especially with Ron, he's probably 7 or 8 by now.
