I kind of knew all along he had it. I am honestly not upset right now. What can ya do? He is acting 100% normal and happy and that is all that matters for now! I wouldn't take it back he is the best cat ever, he has the best personality out of all of them. I love him to pieces and he is what made me love sphynx cats. I think if I would have got Juno first I may not have liked sphynx, shes kind of stuck up. LOL
I'm sorry to hear about Jack. I knew you have long suspected HCM, but that doesn't make take the sting of the diagnosis away. Remember HCM is not necessarily a death sentence. One day at a time. Hugs to you both.
So sorry for you and Jack. Even though you were kind of suspecting, it still is not something you want to hear. I hope that caught early and with the right meds, he will have a long wonderful life with you.
