Monty keeps on trucking. He's been on pills for his thyroid for a while and it's been a process, mainly due to me. I went through the first bottle and waited a couple months and scheduled his follow up. They said, "so he's still on the pills right?" Um, no, I ran out. Vet: "It's a lifetime medication you idiot." So I reload. Make another appointment. Vet: "Ok, so what time does he get his morning pill?" I say I give it to him at night. Vet: "You have to give him two pills a day moron."
Finally got it right and took him in yesterday. Vet just called. Bloodwork completely normal. Vet said "I can't believe these are the results of a 15 year old cat."
We still have the looming possibility of the tumor returning but I'm pretty ecstatic. Monty sitting on me as I type this.
