I mentioned that our cat was sick, so I thought I'd give you guys an update in case anyone was wondering.
After a multitude of trips to the vet, expensive tests, lots of anxiety, force-feeding and hoping for the best, our cat has made a full recovery. From what, we don't know. The vet was perplexed and told us that sometimes cats just have unexplained fever/illness. His best guess was that he got a virus and it made him feel crappy so he stopped eating. Apparently cats like to do that when they're sick. At his worst he was down to 10.5 pounds. But luckily the combination of antibiotics, force-feeding and an appetite stimulant helped him on the road to recovery and when he went back to the vet 5 days later he was up to 12.25 pounds. He's now back to his old self - playing, running around the house, eating like a champ and meowing at us when we aren't paying him enough attention. He and I spent a good part of Memorial Day snuggled up together on a chair. It's good to have my baby back!
