This is a great replacement for kittens, it helps to keep them healthy especially when they do not have their mother around anymore to give them the milk that they need. I have had to use this many times as I like to take in kittens and help out the shelter and feed them when they need someone. I bought this for a group that I had because the pre mixed liquid kind they had they were completely out of. I figured that this would be just as good and it would be like kitten formula. I measured it out and mixed it with water, which is very easy to do, and found that it stayed kind of clumpy. It was really hard to get all of the clumps of it out and get it well mixed. The kittens did not seem to mind, they enjoyed it and thrived on it. It smells really bad after you use it, so you need to make sure that you wash the bowl make it in out right away because if you don't it is going to start to stink really fast. It is great for kittens and always helps make them gain weight and stay healthy.
