Works same day-essential

My doc recommended for my feral rescue kitten for diarrhea. We had him dewormed and his poop was runny and smelt like he had a demon and his demon friends inside

My doc recommended for my feral rescue kitten for diarrhea. We had him dewormed and his poop was runny and smelt like he had a demon and his demon friends inside him. After one day, the diarrhea was gone and the demons left, but return every once in a while. Great product.

My cat refused!

My cat took his first dose with ease. It was a war zone for day 2. I didn’t even try on the 3rd day.

It worked

We adopted a young male cat from the shelter who had bad diarrhea- no worms, etc. The probiotic was easy to give and cleared up his system very quickly. Now
