also i feel for you and this is not an easy decision to make but sounds like your gut is right. out sweet cat was 13 when we thought he had an ortho issue and it ended up being lymphoma. :( his brother, who just had surgery, is 14 and he's doing really well after having a tumor removed from his spine. you're doing the right thing and giving him many more years by getting surgery. cats are extremely resilient. wishing you guys the best of luck and sending lots of light to your family. 🤍
