Hi, I have a male F3 savannah I purchased recently and he was possibly diagnosed with stage 5-6 heart murmur. The vet told me he would need to see a specialist to confirm it, and was most likely congenital. That I would need to have x rays, bloodwork, and an E.K.G. The estimate is around $1000. I'm in Orange County, Ca. I was wondering if anyone has info a recommended vet to take him to? Has anyone gone through the same thing? I'm freaked out by the whole situation. He's my first cat, and I love him so much.
