I've used this with several kittens who were either orphaned, or to help a momma out when she had a big litter. I prefer the pre-mixed kind, but the powder is cheaper.

Pros: Cats seem to like it

Cons: can't think of any

I have had to bottle feed kittens a couple of times & I always buy this stuff to do it. They seem to like it quite up bit. I prefer the liquid formula though because the powder kind that you mix yourself is REALLY hard to get mixed up well enough.

Pros: Kittens love this stuff!

Cons: It's kind of expensive

This has been a life saver for many of my foster animals. It tastes great, is easy to use, and is very nutricious.

Pros: Tastes great, healthy and nutricious

Cons: none

I used this for my foster kittens, who were 4 weeks old when they came to me. I started mixing wet food with it, so they gradually got used to that.
I tried the bottle, but the first kitten bit the nipple right off. Fortunately, they were able to manage with a dish.

Pros: most like mom

Cons: cost

This is a great replacement for cat's milk. We recently fostered a 2 week old kitten from the shelter. By bottle, we fed her this mixed with water. When we first brought her home, she was tiny, covered in fleas, and malnourished. After feeding her this for a few weeks, she was able to recover completely. Now she is several months old and thriving in her new home.

Pros: Great substitute for cat's milk

Cons: Hard to mix sometimes
