Vitamin supplement/ immune support.
My cat prince is about 10 years old. So I thought I would try this vitamin supplement. It works great! He has more energy and his fur is so much softer now. I love it. I think it's a really good product and not expensive at all.

My cat loves it
My cat is FVI positive can I recently got this to help boost his immune system he is suffering from a secondary infection and he has been on antibiotics for a while so he does love the taste of this I sprinkled it over hard cat food and he ate it just fine and he ate it while I mixed into his food the other thing I got along with is was the 15 and one multivitamin which has a bunch of necessary B12 and other multivitamins the only thing I do not like is the packaging in the scoop is extremely tiny so you have to dig around to find it inside of the pack which can make a mess

Alternative
I always used Imuquin but sometimes it was hard to get do I wanted to try another brand. So far this is working as well. Benefits are you can use a little less and it is already all in powder form. The other came in little packets. All in all I'd say this is a great alternative.

Easy to use
My cat has severe stomatitis. The usual treatment is to pull all of their teeth. I did that. Cost and pain aside it did not improve his condition. I was told 20% dont respond to this approach. So now my boy is on a lifetime of steroid treatments. It is an autoimmune condition and my vet recommended this product. It tastes good, or so my cat says. It comes with a little scoop and I mix it with water and he drinks it. It is supposed to support the immune system, and I think I am able to dose the steroids furthur apart. The only drawback is that it is a small bag and kind of pricey.

Our cat did not like the taste
I don’t want to affect the review by giving 1 star thats why I gave 3 stars.We have 2 cats.Both of them didn’t like the taste.And they throw out after eating it. I throw out the package to the trash.

Seems to be working
I bought this for my 17 year old cat who's health was failing him. He looks and acts a lot better since I started this supplement. You just have to be patient. I'm going to buy Dr Bills supplement for skin and coat to add along side this one. I make it into a gravy and he likes it.

Made my cats throw up
I was really wanting this to help my cat with chronic sinus issues due to feline herpes virus, but for some reason it makes him throw up. We tried stopping and slowly starting back and he still throws up when he eats it. As do my other two cats who eat it so that all get the same thing. On top of that, I am not able to return the item so it’s a little annoying.
