At least it's treatable! There is the possibility of surgery later down the road for a permanent fix, bur for now, we're just going to do the meds to get him back to his fat little self.
one of my old cats had that and a heart murmur. He was on thyroid meds for almost 2 yrs. he plumped back up from them and did well until he got sick with his heart issues
calicokitty6: Luckily, there's a pharmacy in town that specializes in compounding vet meds - they make them chicken and fish flavors so it's way easier to give!! had to use that service with another kitty.
we have a place that makes vet meds too. They weren't around when I had to get Sammy's meds. He was on a human med. Regular pharm filled it with "Sam the cat" for the first name.
