Helping my cat.
My cat loves the flavour and it's really helped him. He's stopped over grooming, his hair is growing back and he's much happier and more content. Clearly doing some good.

Great product
Over the years this item has saved the lives of several of my cats. I highly recommend it for your companion animals.

No issues here other than...
The only "con" is the teeny-tiny scoop. I just converted it to 1/2 tsp and that works just fine. Cat will eat it and I've not had any trouble with vomiting.

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.

Waste of money
I should have looked at the ingredients, there are better products out there, I suggest getting a cat mushroom support because the other vitamins in this supplement should be in your cats food, and other vitamin supplements should have more ingredients.

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.

Works!!!!
Noticed a HUGE improvement on a cat we rescued from the side of the road. She’s struggled since we found her now she is looking and feeling so much better.
