Clawdio's ultrasound results came back today. And they came back normal. That is the structure of his heart is good. However, due to genetics, he has one valve that is not closing all the way. Usually this kind of thing is degenerative and we apparently caught it just at the beginning. There's no real treatment for the fact that my cat is getting older and things don't work the same.
So, next week Clawdio gets to go in for his dental to fix his sore tooth. Then every six months we'll go in for check ups and he'll get an ultrasound once a year to monitor his condition, so we'll know when he starts to deteriorate and hopefully prevent him from having any pain and be able to help him with any meds further down the line.
I know a lot of people know this. But getting old is a bitch.
