These can be great time savers for multi-pet households or for large pets that drink a lot of water. They come in a variety of sizes to meet your pets' needs. But keep it clean and don't let it become an excuse not to give your pets fresh water!

Pros: Time saver

Cons: none unless you don't clean it

One of my cats has an allergy to plastic--its not too bad, but he gets chin acne--so I only use this if I'm gonna be gone for a few days. It works well and it keeps the boys watered even if my cat sitter can't make it over everyday.

Pros: works

Cons: plastic

This would've been great if my cat's couldn't knock it over all the time.

Pros: more water

Cons: knocks over

I love this product. I use it for my cats. It is easy to use and a good price. I like the fact that it isn't huge and forces me to fill it everyday. This ensures fresh water for the babies.

Pros: Fresh water

Cons: None

I have 2 of these in the 1 gallon size for 4 dogs and fill them every other day. These are great. If I had water bowls, I 'd be watering them every few hours. Handy dandy product!!

Pros: Very convenient for keeping the water bowl full.

Cons: ?
