Funny you should mention paw pads.

Tubby was sleeping on the chair this weekend (one of his usual spots) and I happened to notice his pads - don't know why I haven't noticed before this - but he has, like old man pads. They look old, wrinkled, kinda dry and cracky and they're all black. I did take a picture, but forgot to bring it to work with me. Cookie's pads are so pink and soft looking - the complete opposite of Tubby's.
