Dudes, she was a kitty mama, ok? Yeah, so she's let herself go a little, but a lot of that extra kitty is uh... big bones and ummm... lots of fur. Yeah, fur. Plus, I tend to catch her when she's laying down (spreading out?), which is apparently not a flattering angle for her.
Anyway, she wanted me to let you know that she's not insecure about her weight at all, and she's quite pleased with herself. Quite.
