Wow, it has been almost a week since I last posted. It has been a busy week. On Monday morning Soots seemed listless, and he didn't perk up during the day. He didn't want to eat or drink. (While we were at work my mom kitty-sat.) We ended up taking Soots to the vet after work that day. (I reached the after hours number of our veterinarian's office for some advice. The vet called back and offered to meet us and open up his office to check out Soots. We have always been loyal clients anyway, but that REALLY sealed the deal!)
Soots had a fever and was a little dehydrated -- probable upper respiratory infection. They gave him subcutaneous fluids, started him on an antibiotic, etc. After a couple of days Soots perked up. He is now playing like crazy and eating like a horse.
