Update: We visited him last night and the nurse brought him into the examination room for us. She commented on what an amazingly good kitty he was. I knew that already
He was still out of it from the anesthesia, but started purring the minute I touched him. His back legs weren't working so well, so he kept sliding around. I brought him his McDonald's (fancy feast) and some dry I/D. I let him lick the FF first and he practically bit the can apart. He was soooooo hungry. When I gave him the dry, he couldn't get enough of it! What an appetite! I didn't want him to eat too much and upset his system, so I fed him in bites every 5 minutes. They let us visit with him for a half hour.
Then when the nurse came back in, he meowed really loud and looked like he was having a seizure. He just kind of looked all spacey and couldn't hold his head up. Then in 10 seconds he seemed fine. She took him in the back for the doctor to check him out. He came back in 5 minutes later and said it was a reaction from the anemia. He decided it was time for a transfusion, which we agreed with. He was also going to give him steroids right away. Depending on what the biopsy says, they will start him on L-asparaginase (chemo) today as well.
I'm nervous about him coming home. I'm going to be watching him like a hawk.
I hope his strong appetite is a good sign for him.
