I Believe It Saved My Cat's Life
I couldn't rave about MYOS enough. For 3 years I'd struggled with my senior calico cat Marble to gain and retain weight. As a petite framed cat already, weighing 7.5 lbs at her heaviest, it was alarming when she started to lose weight in 2020 going from 7 lbs to 5 lbs within the span of 5 months and she began to act more and more lethargic. MYOS was our 9th attempt at helping her gain weight and it helped Marble gain and retain the weight as soon as we started! She even loves the flavor of it, refusing to eat her dry food until it's mixed in! A picky eater to begin with, she will clean a full bowl of her prescription dry food AND her supplemental wet food three times a day. She's much more filled out at a lean 6 lbs as of October 2023. Even now at 15 years old she's still able to jump to the top of our lifted bed with ease, and climb to the top of her cat tower near the ceiling with no additional supplements or medications needed. Her quality of life has so dramatically improved thanks to MYOS; I couldn't thank them enough for helping save my beloved Marble.

Punky is spunky again
My 18 year old cat Punky was losing muscle mass in his hind end as well as energy overall. He gets a scoop of this every morning in a serving of wet food and eagerly eats it up. He's now bouncing around with a noticeable increase in vitality! He's playing a lot and getting into trouble, just like he was when younger. I'm pleased with this supplement.

Good product worth the expense in health and length of time lasting.
Seems expensive but lasts long. And seems to help him. My cat is super fussy and 20 years old. I started small amounts and mixed with little water and a bit of canned food he likes. In a more flat dish. But my cat is super fussy to the point of trying to out smart him.🤣

Great weight builder
This has been a game changer for our 15 yo cat. He had a bout of sickness earlier this year and lost a bunch of weight. I researched supplements and found this. He’s regained all his weight back and some and looks like a much younger version of himself. He eats it with his wet food. Highly recommend.

Myos Feline Muscle Supplement
I will be ordering this product again. My cat is a very fussy eater and I had no problem adding a scoop to her food once a day. She ate all of her portion.

Didn't work for mine.
Been using this for my senior cat with a hyperthyroid, no change. May work for a cat without Hashimoto's.

Don’t recommend at all
My cat absolutely hate it !! Plus it smells horrible. The ingredients says only has one called Fortetropin but allergen says egg. You can’t hide it in anything because if you try to mix it becomes a sticky consistency that ANY cat would have. Just a money grabbing scam

Made a huge difference for my boy!
My boy suffered from a blood clot that paralyzed him 6 months ago, resulting in him having a hind leg amputated while the other remained paralyzed. He lost a lot of muscle because of it. While he worked to be mobile and we took him to physical therapy, it was only until I discovered this product that he started gaining back muscle and standing better on his leg. In only 3 weeks, we could see a vast improvement! Unfortunately, he passed away less than a month later. Highly recommend not just for preventing muscle loss, but also for building back muscle. Photo shows how little muscle he had. Video is of him 3 weeks into taking Myos. The muscle difference is amazing. I wish I had found this product sooner. later. Still, Myos gave him mobility and made his last month with us even better 💙
