Is it safe for a 16 year old cat with kidney desease to have the iodine injection treatment for hype

Her thyroid level is 4.2 (should be less than 3), and her kidney BUN is 53 (should be 20) and creatnin is 3.2 (should be less than 2) (according to the vet). Anyone else experience something like this?

    You need to consult with a vet. In fact many of the places that do I131 treatments want you to consult with an internal medicine specialist before coming to their facility. If you haven't consulted with an IM specialist then it may be worth you while to do so. Each facility is different as to which cats they take depending on their health status so this really is a question for your vet.

    I agree with Hunter that only your vet can tell you for sure. My friend's cat is having the iodine treatment in two weeks and she said that because the kidneys are used to filter the chemicals from the treatment back out of the cat's body, they will not do it for a diabetic cat. With diabetes, the kidneys are already being taxed by the disease and it would most likely not be safe to do the treatment for hyperthyroid. Only specialized facilities do the iodine treatment so they would be the best resource for the information you need. Her cat Meeze does not have diabetes but she still needs a chest xray and additional tests before they will consider doing the treatment. She felt that it was the better choice for her cat rather than a lifetime of pills twice a day. But Meeze is only 8 and is not diabetic.

    You should always treat the thyroid with meds to get it into the normal range before doing radioactive Iodine treatment. High thyroid levels can often mask kidney disease by making the kidneys work more efficiently. You'd probably find that your cats kidney values would get worse as she takes meds/gets iodine treatment to lower her thyroid levels. Some vets choose to keep the thyroid level slightly high in cats with kidney disease but there are also other approaches as that can causes longer term problems. Your vet should have discussed all the kidney/thyroid treatment options with you and also explained how serious the kidneys issues can be. From your question they don't seem to have done that so I'd recommend looking for another vet. Try to get one that specialises in cats as you'll get much better treatment. Kidney and thyroid problems are very common in older cats and there are a lot of good treatment options, but you need a good vet to help you.

    I am not a veterinarian, but have dealt with my own cat who died a year ago from chronic renal failure. In my opinion, you SHOULD NOT put your cat through the iodine injection treatment. Was this suggested by your vet? I don't believe any knowledgeable vet would suggest such a thing. The best advice I can give (from my own experience) is to feed your cat a veterinarian prescribed canned food which will put more moisture in your cat's diet. I used Royal Canin veterinarian prescription diet. My cat actually loved it! The other thing you can do is administer subcutaneous fluids if your cat will tolerate it. It only take five minutes and your cat will feel better. I did this for 14 months and it made my cat feel better. Yes, your cat's kidney values are on the high side, but probably can be managed with the correct low protein, low phosphorous diet a cat suffering from kidney disease needs. As for the thyroid problem, I don't think 4.2 is so bad. Address the kidney problem.
