in the winter this is great for not having to worry if your animal is outside and their water is frozen

Pros: wont let water freeze

Cons: none

This is great to ensure outside dogs always have water. People do not realize how easy it is to forget that water freezes and the outside animals don't have a way to drink.

Pros: easy to use

Cons: not sure

This is a great product for the kitties in the horse barn. Winters can be long here, so this keeps fresh water available. The kitties are all "fixed," by the way!

Pros: Great for barn kitties

Cons: none

We use these in our outdoor runs that we house rehab opossums in. They keep the water free from ice and we know they have a constant supply of water.

Pros: great for outdoors

Cons: none

I love this product. I can leave my kitty outside (Where he has a heated home), for a night or two and not worry about his water freezing up.

Pros: Always provides water.

Cons: Plastic seems to attract dirt.
