Thanks, my friend. I nearly lost a cat whose heart is so enlarged it takes up most of his chest cavity, he was given a day or 2 to live. I wasn't about to settle for that and asked to find out what caused it and fix that and see if it would help his heart. Turned out that his thyroid was triple what it should have been. He is was on heart and thyroid med and just lay gasping for a week, I checked on him every time I got up during the night too. At 5am when I awoke, after a week of this, I went to check and realized he was walking down the hallway beside me. I turned on the light, he was weak and wobbly, but you can imagine how thrilled I was to see that he had made it. I picked him up and was just saying over and over, "Charlee, you made it, you made it?" That was about 4 years ago now and he is still on thyroid med, and doing well. His heart will never be the same, he tires easily and not as lively as once was, but still seems to be getting better. He is back to playing now, and likes to roam around the yard a little, gets tired, and comes in for a nap. He is the joy of the household and there is no way I could just give up and let him die. He is a most loving cat, who made it to my house after being thrown from a passing car.

My eldest cat who passed away 11 years ago now, was 20 when she passed. They told me to not give her much time after being diagnosed with thyroid problems but I put her on the meds, and wow did that help!!! She was 14 when she was diagnosed and lived for another 6 years thanks to the meds!!! :)

Wow, that is great, Cher. I think we never stop missing our pets when they leave us. Charlee was running around playing one day and was dying the next day, that is now suddenly they can be sick. He had no symptoms of anything, until that day and he just wasn't acting himself and called the vet and took him in that same day. So glad I didn't wait another day.

If we believed the vets for every time our precious friends should be "put down" for their sake, than I wonder how many of us would still have our friends. Two of my babies were born in a meth-house, I found them in a trash can. The vet said because they were so young, not more than four weeks and their lungs were filled with this toxic drug, they had no chance at survival. They are now 6 years old, healthy, happy and PURRfect precious.

So true, Kit, we can't just give up on them. It can drain a small savings account, but if we love our pet, wejmust try to save them. After all, they are part of the family, and really rule the house. lol

Like Cher, I had a similar experience- the meds helped tremendously, and gave my cat years.

Good information. My cat is 16 and has been on the methimazole for several years now. I didn't know anything about an enlarged heart. I will ask my vet about this. I knew about the therapy but don't think my cat will allow to be contained for 3 days. She is very spoiled and when in a cage, refused to eat, drink or go potty.

This is timing --my 16 year old Simba has been on Methimazole a few months, but is vomiting every night. We're trying Hills YD now (Vet approved for hyperthyroid) & will do an ultrasound a bit later if needed-maybe more going on. Very worried. Thanks Cher & Ruth~
