We've been noticing that Emily's appetite seems to be better, and the monthly weigh-in confirms it. She's back to 7.0 pounds, from 6.5 last month. She feels better, too, less like she's wasting away.
Whitey is stable at 13.0 pounds.
Billy is working to maintain his Catzilla-like figure. He's all the way up to 15.5 pounds, up a full pound from last month. I'd be worried, except he still looks sleek and is as active as ever. He's just plain big. Still, since he's visiting the vet next week anyway, I'll be sure to get an expert opinion.
