We love this. We used these for our gerbils and even clip it on the cat's dog cage! The cat drinks out of it! It is so simple, doesn't spill or leak and is so convenient.

Pros: Doesn't leak.

Cons: None

This works for my small animals, does not leak but alittle.

Pros: works good, alot of sizes

Cons: none

I like to color coordinate. I am a girl, what can I say. I have purple for my purple cage, blue for my boys. It is silly, but it's me.

I find the seals to be good in these bottles, they don't drip as muchas others I have tried.

The only downfall is that they are a smaller volume than others I've found.

If you have a way to deter algae growth, let me know.

Pros: Fun colors, good seals!

Cons: Smaller size than some other's on the market.

Some of the water bottles in our rabbit rescue are the Oasis brand. They have held up well, after much use. I really like these lids/spouts, too. They are my favorite.

Pros: sturdy, leak proof,

Cons: none

We always have at least one of these handy for the gerbil or guinea pig. Keeps water fresh.

Pros: none

Cons: none
