What Pet Owners Are Saying
Helped my 6-month kitten recover from a cold. I use it every day and have noticed an improvement with his confidence, energy, and allergies. He also seems to be calmer and sleeps soundly. Thanks for a great supplement for kittens/ cats.
Quality ingredients. This supplement has noticeably improved my cat’s general health and attitude. Highly recommend.
Antioxidants for Dogs
I love that this product has tons of natural ingredients and antioxidants in it! My dog is a breed that has a higher risk of cancer, so I use this as a preventative measure. So far, so good (any my dog loves the taste!)
Have been adding this to the diet of an extremely fussy cat and he is now gaining weight. I highly recommend this for young, ill, senior, or just plain fussy cats. I will be ordering this again.
My dog loves this. He eats it off the top of his food before he eats his food. This product is great and he is feeling so much better.
