Could have been catastrophic

I was (mistakenly) told at the shelter that this is what was being given to the bottle kittens I was fostering. My intention was to purchase KMR but felt like since this is what they were being given I shouldn't change them. They had constant diarrhea. I took them back to the shelter, they tested negative for parasites and the condition cleared up when they stopped giving this.

Works perfectly

I started with two one-day old kittens.Now they are four weeks old. First 3 and half weeks they lived 100% on a slurry of this powder in slightly warm water fed by bottle. They did great. In latest week they are now 50% kitten milk and 50% kitten wet food. They are healthy and energetic. Great product
