I've used both this and a competitor's product on the same bottle baby kitten and the competitor's product gave her horrible diarrhea (after taking several days to switch her to the other product) but once the diarrhea began I immediately bought this product and switched her back with no gradual switch over period. Within days her stool firmed up and she was nursing much better than she had on the other product. This stuff is GREAT and I'll be using it on every baby I raise from now on!
Tired of paying so much for KMR, I started to look for alternatives. I read a lot of labels and, while I am definitely not a nutrition expert, I was most impressed with this ingredient list. It has things that others do not, and overall gave me the impression that a great deal of care and thought had been placed in constructing this formula. It mixes easily and my cats love it, and the price is reasonable. I doubt I will ever move away from this one.
