I have used these and haven't had problems with them.

Pros: Work great for orphaned kittens.

Cons: None.

It is great to have a brush that fits the bottle. It was so hard to clean the bottles good with no brush. Love the conveince.

Pros: clean ease.

Cons: none

I have used the Just Born bottle feeder for everything from newborn puppies to baby bunnies. It is much easier to use and more convenient than an eye dropper. The only problem I have had is the milk substitue clogging the nipple but this is a problem with all such products. I would definately recommend to anyone who deals with small newborn animals.

Pros: Easy and convenient

Cons: like any bottle, the nipples get clogged with frequent use

only had to use with one of my moms litters but it worked very well, wasnt costly and easy to clean

Pros: good quality

Cons: none

This product was a life-saver when our last litter was born. We supplemented the mother's milk for three puppies with these bottles and they were all healthy and strong by the time they were weaned. The only problem we encountered was as the sucking reflex got stronger, the bottles would "collapse". They regained their shape afterward however.

Pros: Handy, convenient size

Cons: Can collapse if the puppy sucks too hard
