Two week update:

Ozzy went in for his weekly weigh-in this morning, much to his dismay. I had to carry him into the clinic, but he dragged me right back out once he realized he didn't have to stay today!

In two weeks, Ozzy has gained 5.5 pounds! He looks much better, his spine doesn't stick out anymore! He's eating an unbelievable amount of food, but apparently that's what he needs. I'd like him to gain a couple more pounds and then I'll have to figure out what he needs to maintain his weight!
