I think Ivy is going back to his breeder or original owner.

I'd talk to the breeder.

I wonder if the breeder or the owner would treat him for his conditions?

Otherwise...I wonder if there is someone, either on PT or elsewhere, that would be willing to take him on.

Oh, Buttercup, I'm so sorry! I just love your boys. I know this is an awful situation for you. Just know that you, and Ivy are in my thoughts, and prayers.

That's strange, because my heart cat Marius has a grade 3 heart murmur, and my vet indicated that it's really nothing to worry about at this point. Marius never had a heart murmur before, so having it appear suddenly (about 3 years ago now) was alarming. They did an ultrasound on him and discovered a grade 3. He doesn't require meds at this point, but I do have to keep a close eye to see if any of his behavior changes. My vet told me that as long as he's acting normal, that there's nothing to worry about. I'll just have to bring him in once a year or so to make sure it's not advancing. That was 3 years ago, and he's still consistent, which is good.
I would ask for a second opinion? How is Ivy acting? Is he behaving differently/more lethargic? It seems to me that they're treating this grade 3 as a grade 5 or 6, but maybe they use a different scale?

Regarding what to do with him if this really becomes serious, it probably would be in his best interest to go back to the breeder. Good luck and let us know what happens!

WolfLady going to the vet I work at was my second opinion. I had already taken him to a vet which is how I discovered he had the grd 3. They mark it on a scale of up to 6.
After hearing you say that your vet said it was nothing to worry about it makes me think if I gave him back it would be for no reason and that I would be wrong.
How he acts is kind of weird he has this odd routine it seems. One day he will just sleep all day and not move from that spot all day, not even to eat or drink and usually the next day he is more active (active as in walking around the house and eating/drinking). Sometimes though he stays sleeping for 2 days.

The only thing I'd worry about with sending him back to his breeder is that he would have to fly and he's not UTD in shots because of his stupid previous owner. I wouldn't want to put more stress on him with his heart because with high murrmors they can have heart attacks more easily.
