I picked him up at the vet today and he's doing so much better. His eyes are sparkling again and he seems to feel so much better. He walked at the vet's earlier and ate. The girls at the vet even commented on his improvement and how much better his eyes looked!
Once I got him home, he walked a little bit too :) He was looking antsy on the couch so I took him in the kitchen and put him down and he walked over to his pee pad and went potty. He's really improved a lot since yesterday. His mood seems better too. He seems happier and you can tell he's a lot more comfortable.
