    Vitamins for cats

    By folkartnmore on Jan 16, 2022

    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!!!

    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

    By Buyer on Jul 10, 2021

    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

    By dmmc on Nov 24, 2020

    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.
