I recently found 2 abandoned 3 week old kittens. They were pretty thin and in need of a good meal. I don't know how they ended up in my yard but their was no mother cat to be found. I knew that I needed to find a kitten formula asap. I went to my local big box store and this was the only kitten formula that they sold and I was in immediate need. So I purchased this and a couple kitten bottles to feed the kittens with. I made bottles as soon as I got home to feed these poor little babies and they loved this formula! They just couldn't get enough! I fed the recommended amount. And continued on for a few days. I noticed that the kittens were gaining weight nicely. They were filling out and not looking so thin. A week later they were thriving. The kittens looked to be at a more normal weight so I continued feeding the formula and added a little wet cat food with it to keep them full a little longer. They are now at an age where they are no longer bottle fed but I continue to use the formula mixed in their food to ensure that they're getting the necessary nutrients for small kittens. I will continue to do this for about another month before I wean them. Quality of Ingredients This product seems to have the necessary ingredients to produce healthy kittens. Flavor Selection It comes in one flavor. But a selection of flavors isn't necessary. It needs to resemble the taste of mom cat's milk and it seems to by the way the kittens went crazy for it.
