good addition

This product was suggested by my holistic vet. It's a nice addition to my dog's diet. My dog has never had a digestive issue with it. He will be 15 two months.

Very Disappointed

I bought this product to add to homemade cat food. The color and smell of this product was horrible and not surprisingly, my cat will not touch anything this product is added to. Extremely disappointing.

waste of time and money...

smells like moldy dried grass ground up into a powder. Tried the recommended less than 1/8th teaspoon in baked chicken cats wouldn't touch it so I tried a tiny pinch in with their bowl of kibble and one cat took a few bites and 10 minutes later vomit it out. I prompty discarded all the chicken and kibble that i had contaminated with this garbage and put it where it belongs in the trash. Chewy covered the refund minus the shipping I was happy to pay only the shipping to escape further damage to my cats

Allergic Reaction

Used this product for about one week after which time my cats developed sneezing and itchy skin, one cat chewing the fur off both back legs. They had no previous issues with allergies either from food or environmental.

Vitamins for cats

After having my 7 indoor cats on these vitamins for a week, I found it upset their stomachs. However, I added pumpkin flakes to their food which solved that problem. They are all playing like kittens now, even though they're 5 to 12 years old, with only 1 as young as 1 year. They FULL of energy & obviously feel so much better! I absolutely recommend these vitamins!!!

Love the Powdered form

I was having difficulty finding a vitamin that I was able to give to my senior dog--I have been making homemade food and needed some assurance that she was getting everything she needed---

Not happy that there is no scoop

I was not happy that there was no scoop in the container. I had to buy my own scoop, but it was smaller. However, I am happy now that I use less and the container lasts LONGER!!! It is all good. Thanks RX

Quality supp

My holistic vet recommended these for my 13 year old shiba inu who eats homemade food. I think they work well. She is the healthiest senior dog I've ever owned. The powder tastes good to her as well.
