Indy is 16 years old now. He has been through so much. Pneumonia, a three month stint of anorexia complete with feeding tubes, and cholangeohepatitis. That last one is recent, and there are former blog posts all about it. He has also been through several moves, Matt moving in, cats moving in, fosters in and out and the loss of his first feline companion. Through it all, he has been a rock. He is a strong cat. He is very vocal and he is the leader of the cat army. Cat groups are not really determined by alpha, or top cat. Some believe they form a hierarchy. I don’t really think mine do. If they do, it’s Indy at the top and everyone else at the bottom. He has taught all the others that they accept each other and be nice. He breaks up fights. When Blossom tries to test his authority, he literally takes her down – body slams her. He never hurts her. He just says that he won’t tolerate her foolishness.
But now? Sigh. He has to admit to being old. Sometimes, Blossom gets away with that foolishness! He won’t stop her. When he was diagnosed with the cholangeohepatitis, he was also diagnosed with a small bit of arthritis. I guess that happens to the best of us. But in January, when we took him in to the vet for his usual 6-month senior comprehensive physical and blood work veterinary visit, as all senior pets should have ,we found out that he had developed hyperthyroidism – and that his liver enzymes were once again elevated. UGH.
Well the good news in this is that hyperthyroidism is completely curable. I’ve always said that if my cats have to have one of the big three cat diseases – kidney failure, hyperthyroid, diabetes – I would choose hyperthyroid, because there is a cure. It is called radio-iodine treatment, and it is one shot, given subcutaneously, just like a vaccination. There are downsides to the treatment which are a three day hospital stay (which can happen to your cat for any number of reasons anyway), and either having to save the fecal matter in a plastic bag for a few weeks before disposal or flushing (I chose the former). There is also a slight risk of kidney damage, or that if the hyperthyroid is severe enough, the one treatment won’t be enough, and it would need replaced. And it is an expensive upfront cost of $1,200. But the upside trumps all of that – it IS a cure (even if you need the second round).

Left on its own, hyperthyroid eventually wears down the other organs, liver, kidneys and heart, and it wears them down faster than if they would on their own. So you definitely want to treat it in some way. Other treatments are surgery, although that is not done very often these days, and treatment with methimazole. There are pros and cons to methimazole, and it can control and slow down, but not cure the condition. One of the big downsides however, is the fact that the medication itslef can be harmful to the liver. And as you just read, Indy was already compromised.
Eleven years ago, when our Joey was only ten years old and diagnosed with hyperthyroidism, we opted for the radio-iodine treatment, which back then was a brand new treatment. His T4 levels were very high – 22 (normal .4 to 4) - and it was expected that he would need to have it done twice – and he didn’t. He never had a recurrence and never had any health issues until he was 16 years old old and developed kidney disease, which he had until he finally died at nearly 21 years old of heart disease.
Believing that getting the thyroid function back to normal and hoping that the thyroid was causing the liver values to be off, and having such a positive previous experience, we scheduled Indy for his radio-iodine treatment and waited. We took him in two months later for his follow-up blood tests. His thyroid was totally normal again, as expected. It wasn’t that high, so we didn’t expect a different result. His liver values did drop as well, although not back into the normal ranges quite yet and we were hopeful that they would continue to drop. A few weeks after treatment, he started to give us difficulties with eating as well. He just wouldn’t eat much – his treats always. But a few times, he ignored those and he also refused bacon. Bacon. Uh-oh. To the vet he went. To our dismay, kidney values were elevated. We force fed him a few meals, gave him fluids and in a few days he was feeling like his old self. I continued him on fluids, and made an appointment to take him back to the vet in one month. That appointment was this past Monday, June 6th.
The good news from that visit is that he pretty much maintained his weight. But the results of his blood work are not very good. His BUN value increased, although the creatinine, which is the more important factor, only went up to 2.8 from 2.6, so hopefully, the BUN was only a result of dehydration. His liver values started rising again as well. So now he is on the Joey regimen: fluids 3x a week and bi-weekly acupuncture. We will add liver meridians in, and are going to try calciferol, which is a vitamin D derivative which is showing promise in treating cats with kidney failure. On his next visit, I’ll talk more with the vet about supporting the liver, but poor Indy is already on a daily vitamin that he takes once a day, another kidney support supplement, glucosamine treats and then the calciferol liquid coming soon (I’m getting it compounded and I hope I can get it made in bacon flavor – that is his favorite).
So this was a depressing post. Go back and read the kitten post! Or check out cute overload! Or some LOL cats.
