I stared this thread because there is no new reports or updates with long term study of people using the new y/d prescription food for feline hyperthyroidism. So I hope to encourage people that are using it to post updates or problems they are having with the food. Updates other than he or she is doing great or not great, but a little more in depth as it will help us all understand what's happening with our felines body other than maintaining the T4 levels.

Sylvester, my 16 year old tuxedo cat was diagnosed with it about 4 months ago. He's been on the food instead of the other options for treatment. His levels did go down from 9 to around 4, and his behavior has toned down from the erratic spurts of energy, late night meowing, aggressive eating, and overall restlessness.

However, since being on the food I've noticed his deterioration in his lower back and his urinating/pooping. The food is not a healthy balance when it comes to a felines protein intake, and the dry food is even worse than the wet. Which is why I feed him the wet and dry is just in a bowl for snacking. It took many alterations of the wet food to get Sylvester to eat it once the newness wore off the first couple of weeks.

I experimented in giving him a little, little of his gravy food by Fancy Feast and broke the rule of giving him only this y/d food only as directed. They were right, his erratic spurts and symptoms came back within a few days. So, they have to be strictly on this diet for life.

Sylvester has had a massive increase in thirst and drinking water. He is going to the bathroom and urinating an extreme amount, and his poop is very little compared to what it use to be daily. Our vet did all the tests, and his urine test showed early stages of kidney disease and that he was in-taking a unusual amount of water which is not normal, but keep plenty for him to drink as it's getting rid of waster. They gave him a enema and that seemed to help.

My question now is the food causing his newly problem? I have to mix water with the wet and add a few kibbles of the dry y/d to get him to eat it. I also have to give him smaller amounts as he leaves so much to waste, and this food spoil quickly if left out.

Is this food causing his lack of pooping and constant licking his lower back to the point his hair has thinned tremendously? Is he going down hill because of this food acting on his kidneys or digestive track? If so what is the best option of 2 bad internal problems? Take him offf the food and let him go back to his more nutritious food, or keep on the y/d and let the unusual digestive/kidney problem possibly worsen? If that is indeed the cause of this?

As you can tell there is so lack of research done on the pro longed affects using this food, that I hope others will share their similar or non similar problems on here so we all can get a better idea of what's going on and what we need to do for their short lived future. I'm referring to cats 10 years +.j

My Vet, like many, are on the same education level as I am on this food, because it's so new. So, I'm just concerned how fast is Sylvester going down on his rear, possible kidney problems, renal failure, etc.. because of this food? OR is it just coincidence he's developing these problems because of age?

Personally I feel the food is causing his urine/poop problems and contributing to his lower back issues, but it works on the hyperthyroid that's for sure.

If anyone has problems feeding it to their cats, I can give some tips that's worked for Sylvester. It's been a learning experience in feeding him, and he's not a picky eater by any means, but his has been a challenge.

Keep in mind this on the food, it spoil quickly. I reduced giving him a 1/4 of food at a time, mash it with a fork, and add a little water to mix it and make it more soft and liquidy. I also add a few bits of the dry to give it flavor and a cat food smell, as without that it just stinks and he's not tempted to eat it.

Fridge the rest, sealed as it will turn in the fridge  if not covered. When I feed him again, I don't have time to wait for it to defrost, so I do the above again with a fork, and add hot water over it, and poor it off, then a add a little more hot and mix it in. Just make sure you don't serve it with hot water. You can also briefly, briefly microwave it and add water.

So, that's about it and would love to hear any experiences with this food good or bad from others and any symptoms or problems with anything else, as well as, their Vets advice.

Sylvester and I are very connected with our Vet and Dr Arnold in New York, or better known as, Cat Man Do. So, all we can do with Sly is wait and see test results later on, and basically watch him. Which is the hardest thing to do, because we all want the absolute best for our felines.

BTW, the other options for treatment on his thyroid is out of question for us personally, which is why we went this route with the food. That includes surgery, radioactive treatment and the pills.

Thanks,

Jason and Sylvester.

Curious, why add hot water then pour it off? It seems like that might wash away nutrition.

It warms it up with the hot water so it's not cold right out of the fridge. It doesn't wash nutrition away. :)

The pills are entirely to hard to give to Sylvester, and it causes him more stress and anxiety, so I don't want him to have to go through that on a daily basis for life. I rather him be as comfortable as possible.

Also, I know some are thinking well just mix the pills in his food. Sylvester can distinguish the slightest amount of medication in his food. He battled ringworm fungus right after moving down here to Florida, and after no luck I opted to give him the expensive medication. It was a unbelievable hassle, and finally I gave up. Thank God he got over it, but I think that started the whole down hill thing with him. I say down hill, but he's actually doing well for his age.

What about transdermal methimazole?

And taurine is water soluble (as are most amino acids), so yes, if you are draining the water away, some nutrient loss will happen.

I work with the Vet in New York via email and phone, unfortunately I live here in Tampa. I might look into the treatment by ear. I didn't know they made it in that form. Sylvester has been batteling ear problems/infections ever since moving here, so I hope that wouldn't affect his ears, but I may look into that. Thanks!

If anyone has had experiences with the topical methimazole, please let me know.

My biggest concern on this food is because the lack of protien, the cat's body breaks down muscle mass to supliment, and I can tell he has loss muscle mass especially in his rear. I just don't know why Hill's didn't add more protein to this food.

Vball does that treatment cure the thyroid or just keep it managed like the food does?

Thanks! :) I don't know why my vet didn't recommend this option, especially since she knows he's now having problems with his rear.

I don't know why my vet didn't recommend this option
First, are you actually dealing with Dr. Plotnick himself......or one of the Vets on his staff?

And then, yes, I'm also wondering why you weren't offered the option of transdermal gel by your own Vet........because, any COMPETENT feline Veterinarian certainly would have raised that with you.

What's more astonishing is that, considering the reputation enjoyed by that New York clinic, they would both endorse a completely inappropriate feline diet (read Dr. Peterson's evaluation of this "food" *) and not suggest the gel.

Yes it's with Dr. Plotnick, I know him. I was surprised to about him and others endorsing the food diet. I know they make money off the food, but I still think they don't recommend it so much because it does work, but no one knows the long term affect as it's stil to new of a treatment. I've read Dr. Perterson's evaluation, but again he doesn't have any proof on long term, and Sylvester is already 16, so it's not like he has a full life ahead of him anymore.

I was just hoping someone had released something new and recent based off tests or studying the food treatment so I would know if this is causing problems with his kidneys or his lower back as in loosing muscle mass. I'm going to ask Dr. Nettlers about the trandermal and see. Sly won't do the pill pockets or anything with a crushed pill in it as he knows if something is in there, lol. We've been down that road before, so that's one reason I really wanted to do this food.

Hi Jason,

I have a cat, 16 years, who is hyperthyroid, has high kidney levels, and has cancer.  I am treating the hyperthyroidism with the Methimazole, 2.5mg per day (1.25 mg twice a day).  As you are looking into other options besides the y/d food, I thought I'd make a couple comments. 

First, you mentioned that your cat's T4 level was controlled down to 4.  It is my understanding (readings and internist vet) that an elderly cat's T4 level should be closer to 2, or ideally just under 2.  For that age cat, 2.5 - 4 is still in the gray zone and can cause stress to his organs.   So, you might want to re-discuss with your vet the best T4 level for your cat that can be achieved with either medication or food. 

As my cat's kidneys have worsened, he has become quite un-pillable.  Won't go near a pill pocket, and trying to slip a pill to the back of the throat (previously a very easy option) is now next to impossible.  I get my methimazole compounded into a liver chew treat.  It is soft, about the size of a chewable vitamin c tablet (which I then cut in half), and my cat BEGS to eat them.  I live in CA, I get them from BCP Vet Pharmacy in Houston.  My vet calls in the prescription, it arrives at my door 3 days later.  Two month supply (at our dosage) is $40, including shipping.  There are lots of flavors, liver works for us.  They also prepare the transdermal gel.  I chose not to do that.  It seems like it builds up in the ear, that then requires cleaning.  This cat has a brother and they groom each other all the time.  Don't need the brother (who's had the iodine procedure) to lick the methimazole.    Anyway, they describe everything on their website if you are interested. 

So, with the thyroid controlled, I can feed great food (I actually do home cooked food) appropriate for his kidney situation, and his muscle mass is perfect.  I hope you find your answer!

:scratch:

His evaluation is that the food is species-inappropriate and doesn't cure the disease. There doesn't need to be any long term follow-up to this evaluation, as it has nothing to do with time.

No, Dr. Plotnick supported the food and did an article on it, unless he's recently changed his mind? There is definitley a long term study needed, as people are using this product as a treatment not just to feed an animal. If this food shows long term problems or causes other problems, then it has to be known so they can either 1. pull it permanently or 2. re-make it.

It would be foolish not to do a long term study on a new product for any animal.

Also, you're correct as all articles stated, it doesn't cure the disease, it maintains the thyroid levels is all it does, and give a cat a longer more comfortable life.
