Yes Yes Yes — Great Product!
Update 6/20/2023: About one week ago we had to give our cat some methimazole to stabilize as he was losing weight and seemed a bit jittery. He was giving off that “espresso shot look” again. …Now we are alternating the BestLife with the methimazole. Update 5/31/2023: Our cat is doing great! The main factor was to maintain weight and the hyper activity. We give him 3 pills inside of a pill picket by morning and 3 pills again at night. Sometimes we miss doses by accident, but he is doing well! Update 5/6/2023: Our cat is beginning to lose weight and seems more hyper so we upped his dose. His weight is usually around 14-16 lbs. we adjusted to three doses per day (2 pills each). 6 pills/day total. Update 4/26/2023: This product has surprisingly been great! We have skipped some evening doses and he acts the same. We have decided to dispense two tablets (based on weight) in the morning and one at night (instead of another two). He is maintaining his weight and everything is normal/ as usual! He no longer has loose stool after about 1.5 weeks. ————- My 14 year old orange tabby (14-16lbs) was diagnosed with hyperthyroidism two years ago after losing weight far too fast, constant hunger and looking like he drank 8 cups of espresso daily… needless to say, our vet did some bloodwork and he has been on methimazole ever since. More recently, I have carefully considered (after thoroughly reading about pharmaceutical drugs) that I highly prefer to go the natural route given the damaging side effects any Rx can potentially have on animals/humans. These little tablets are a God-send! They’re so easy to pop inside of a pill pocket. Thus far, he is on week two and he takes two of these tiny tablets in the morning and another two in the evening. So far, so good! No issues with them going in the pill pockets, either. He is calm, sleeps normally, and eats normally. It was a quick transition from the methimazole. The only negative is a loose stool. I am hopeful it will regulate soon, but only time will tell. I also read someone gives their cat three doses per day. *keeping that in mind for later down the road* Two doses of two tablets per day works great for now. Each bottle is 450 tabs. We are very thankful for this natural product!!

Cat eats pills with no trouble
The last vet visit and blood test showed high levels of markers for thyroid disease. The vet recommended more tests, and either medication or radiation therapy. The medication requires close monitoring, more blood tests and vet visits. The radiation therapy is expensive. I decided to try this OTC pill, based on reviews. My cat is still drinking a lot of water. I have not gone back for more testing, so no idea if it’s working or not. Can’t hurt. He did gain back some weight. He’s in diabetic remission, so I did check his glucose level. It’s high, could be cause of the water consumption, but not high enough to treat with insulin again. My cat looks fine, activity level is normal, appetite is normal. So I will let him be, keep giving this thyroid support , and a probiotic, and hope for the best. Update - it’s been about 6 weeks, and my cat is now drinking less water, and eating less food. He’s now eating the recommended amount of food for his weight, less pee in the litter box. Activity level is normal, coat looks great. I hope this supplement is working!

Was skeptical, but happily surprised
I read a lot of reviews about their cats dying after this medication (which I wondered if the cat was too far in for treatment before taking this medication), reviews that the product was homeopathic and wouldn't work due to no placebo effect with animals and some reviews from people who were recommended this by their vet for pets with sensitivities. I didn't want to take my cat to the vet as she's already anxious and easily stressed and she hates the vet office to the point of shaking when she's there. She's 12 years old and I recognized the beginning of hyperthyroidism. She's always been a small cat, never above 6 pounds, so the weight loss was hard to tell on her. Her back fur kept balding from overgrooming and her nose fur started to go which really got me paying attention. I noticed she was peeing more often and drinking a ton of water, her sister had this issue and she ended up dying not long after I realized the issue so I started looking into treatment at home besides home cooked meals. I started this cautiously, 1 pill for about 7 days just to see how she reacted to it. She was fine, no real issues. I finally started the 2 pill recommended dosage after establishing she wasn't going to have a reaction to the medication and within about 2 weeks I noticed changes already. She stopped scream meowing constantly, she was less aggressive about food and she toned down on the water. I have started giving her 2 pills at the same time every day so I don't forget and she's doing well with that for the last 1.5 weeks. It's been probably near a month and her hair on her back is growing back, the nose is unchanged, but her weight is back to normal and she's back to playing with my other cat rather than lashing out at her randomly. You get a lot of medication in a glass bottle so that's an amazing sign of quality and the results have sold me. This won't cure her, but it will help her stay herself until it's eventually her time to go and I'm grateful for the time this medication is giving us.

This is my UPDATE from "We will see..." review
My Miss Mama is going back to the Vet's on the 6th of Nov for blood work check for Hyperthyroidism so at this point and time I cannot give an honest opinion... I did give 3 stars at this time because she has not lost any more weight and her outrageous eating habits have slowed down to a normal way of eating. My Vet is aware I wanted to try natural opposed to drugs and as long as my Miss Mama was not in danger, I opted this first. I will update as soon as I get blood work results. ******** UPDATE: Just received e-mail from Miss Mama's Vet regarding Her Hyperthyroidism levels PLEASE READ ******* I reviewed Miss Mama's bloodwork results and her T4 level has increased since her last visit. On 10/16 her T4 was 12.9 and yesterday11-6-24 her T4 was greater than 20 (for reference the normal range is between 0.8-4.7). This means that her hyperthyroidism is very uncontrolled. It's a good thing we got her started on methimazole. THIS MEANS THIS PRODUCT IS NOT GOOD FOR WHAT IS IT STATING! I am so glad I listen to my VET and had her levels rechecked and even though I wanted something natural for her, her life means more... so we started yesterday methimazole and hope I did not do her any harm by trying the Natural product. I have changed the stars to 1 and if I could have given 0 I would of due to misleading info from the maker. ALSO PLEASE PLEASE READ the INSIDE PAMPHLET on ANY PRODUCTS you purchase AS I FOUND A NON-NATURAL ingredient in another product from them, again misleading info. I wish product ingredients were somewhere listed on the selling page so we could see ingredients before making the purchase.... would be helpful. Miss Mama will go back in 3 weeks for blood recheck and I hope and pray she will be better, and I did not cause any additional harm by trying a NATURAL product.

This product definitely improved my old cat's health and appearance.
January 2026 update: My 17 year old cat was hit and killed earlier this month, but I wanted to do an update on this product. She took "Hyperthyroid & Gentle Weight Gain Support for Cats and Kittens" for 1 1/2 years and did very well on it, i.e. her condition improved. She continued to lose a little weight, but very gradually. She weighed 7 pounds a few weeks ago, her fur was in great shape (not shedding), she had plenty of energy and a decent appetite and seemed generally happy and healthy. If not for the accident, we anticipated another couple years of good life for her. ----------------------------------- (Aug 2024) I plan to update in a month or two. I have an outside yellow tabby who is almost 16. She has always shed a lot and has been losing weight gradually for 2-3 years (weighed 10 lbs at age 4 and weighs 8 now), but no obvious health problems, per her annual vet visit. Switching to mid-grade Purina dry food several years ago helped her coat (and all the other cats) but the hair loss got worse again this summer along with almost daily hair balls (tubes!). I have been giving her 2 tablets of this product per day for a month, and she has had no ill effects. She may or may not have gained weight (my scale only does 1/2 pound increments) but her back feels less bony and she is no longer shedding or having hair balls. I will update in 4 to 8 weeks.

I was nervous BUT THESE PILLS WORK!!! A miracle
My baby girl is 18 and was diagnosed last year with hyperthyroidism. I took her in because she was restless… she is one of the most chillest sweetest cats but she howled constantly day and night … paced my counters.. she stopped relaxing and laying with me even at nighttime she was awake howling. I would have to lock her into my closest so she would sleep a little bit and be quiet because I work from home. So I took her and in and that’s when she was diagnosed… I’ve had her since she was a kitten and I was 15. Now I’m 33 & I just can’t imagine life without her. I was desperate to find something natural to help her. The doctor advised the medication but I read the side effects and I absolutely did not want to risk it. So I did research and I found the Food for cats which seemed to help a lot! However with that food she hated the hard food so she lost a lot of weight very quickly from switching & from only being on wet food, she also started to she’d like crazyyyyy hair everywhere. Then I found these to try to help her weight go up some! I started her with 1 pill for a few weeks to get her used to it and see how she responded to it. Then I increased her dosage to her 2 pills per day by crushing them in her wet food. LET ME TEL YOU THEY WORK AMAZING!!!!!!!!!!!!!!!!!! SHE IS CALM. We can tell when she hasn’t had them! SHE has stopped losing weight and she isn’t on the special medication food anymore because it’s been sold out for MONTHS!!! Everywhere! SHE HAS stopped shedding as much after weeks of her taking 2 pills daily!! NO MORE HOWLING -thank goodness.. even with the medication food the Doc prescribed her being gone these pills work amazing!! I will say she HAS NOT gained any weight but she seems to be maintaining. I am going to increase to 3 pills per day to see if it helps her gain weight. She still drinks water a lot but not as much as she use too. Without these pills she would be so sick I’m sure of it. When she misses a dose Because she hasn’t eaten me and my hubby can tell 100%. She starts acting crazy again and becomes restless and paces everywhere. As long as we give these to her each morning she is fine! I’ll give you an update about her weight once she’s on 3 pills for a while. I pray it helps. I love my baby she’s my bestie. I really hope my review helps someone else. She’s been on these for about 3-4 months regularly.

It worked!!
My aging cat was getting very skinny and losing patches of hair and crying for food all hours of the day and night, but eating normally. I bought this product based on reviews but was only cautiously optimistic. I have been tracking her weight and she went from 10 pounds to 15 in 4 weeks which I think is amazing (its like a 100 lb person gains 50% of their body weight to 150 lbs) She no longer cries all night, her fur looks healthy, she's visibly fattening up and no longer bony. There are a Lot of pills in the bottle so the value is great. And they are super tiny so it's easy to give to her.

No noticeable difference
My cat couldn't be diagnosed with hyperthyroidism even though it was suspected because she was too underweight and too old to risk putting under to draw blood (she was too upset/aggressive to have it taken any other way). Since I couldn't get medication for her, I went ahead and tried this - twice a day I crushed up the pills and gave it to her with her meals. She definitely ate it, but she didn't really have any change. About 3-4 weeks later I had medication that could make it so they could take blood for a test. I was informed that normally the test doesn't really detected it the first time and they usually have to follow up with a more sensitive test. She didn't even need the followup. Her levels were high enough to show she was solidly hyperthyroidic. Could be her levels had been SO HIGH that these pills affected it, but if so, it wasn't enough to actually help her. The only thing I'll note is she did stop throwing up around the time I started giving her these pills, but due to a variety of things, that's more anecdotal rather than scientific reasoning.

This saved my kitty.
This medication has gotten my kitty (age 13), off expensive vet Rx medication which didn’t work. Now my cat has gained enough weight, from 2.5 kilo to 4 kilo in a year. She is considered healthy, and I can say very happy, playful, and full of energy. I’m very pleased with this medication. I recommend, due to its low price, you at least give this a try, if your kitty is not accepting your vet’s Rx compounded Thyroid medication mixed with food. I thought my cat was a goner. This was my last shot, and it worked. It’s not a fast fix, but it works. Don’t wait until the last minute. Thyroid medication makes your cat itchy, as will this. I have reduced the amount a bit, but 18 months after a weight of 2.5 kilos, I’m so happy that I still have my cat, Ebony, already rescued once. If you’re at the end of your rope, please try this. It saved my cat. My experience. Gail

Bien
Le produit est arrivé rapidement et conforme à la description, ce qui est toujours rassurant. L’emballage était propre et bien scellé. L’utilisation est simple et le format pratique. Mon chat a accepté le produit sans trop de difficulté, ce qui n’est pas toujours évident. Il semble mieux manger et reprendre un peu d’énergie, même si je reste prudente quant aux effets réels sur la prise de poids ou l’hyperthyroïdie — ce type de problème nécessite toujours un suivi vétérinaire pour être certain de bien faire. Dans l’ensemble, c’est un produit conforme, facile à administrer et qui peut compléter les soins recommandés. À utiliser avec attention et idéalement en parallèle des conseils d’un professionnel.

Absolutely amazing!!
I normally do not write reviews, but wanted to share what a difference this product has made in our 13-year-old cat with hyperthyroidism after just one week of taking it. Improved behaviors, stopped howling, pacing, and pulling his hair out, so much more relaxed, and gaining weight.

Pas bon
Après la 2e journée j'ai arrêté ce produit, mon chat a eu des gros mots de ventre et du sang dans les selles. Achetez pas ça. Je donnerais zéro étoile si je pouvais.

My 11 year old cat didn't gain weight.
Gave it to my 11 year old cat. To me it doesn't work. Pills are way to small and she didn't gain weight.
