This is the second tub I have used and it seems to be working well for my boy, he's 10 years old now so I have to keep an eye on his digestion.
I was advised to try a probiotic so far so good.
Very easy to use. I put it in our cat Rudi's food once a day. He never turns his nose up at it & it keeps his stomach healthy. Great product & i'll keep using it. I can thoroughly recommend.
