Spock is carrying a little extra weight these days himself. Since we changed his food, I think I must have been throwing a few too many kibble in his bowl, and he's now up to 30 pounds. I've been cutting back on his food for the last few days, and he and Bones have been more active, so I'm happy about that. Bones is tiny and svelte at 24 pounds; I swear it's all muscle.
