The rating categories for a water bottle are a bit strange. Enjoyment? Healthiness/vitamins? Stomach upset? Taste? Huh? After my daughter rescued some mice who were going to be destroyed from her high school, we used various water bottles. These work just fine.

Pros: Works fine for mice

Cons: NONE

I've had these be a hit or miss. Sometimes they work... and sometimes they leak.

Pros: sometimes works

Cons: Sometimes doesn't

We have a cat that will not drink out of a bowl. He drinks from our filtered water spicet. We thought if we could mount something like this for him it would be great for when we go on vacation. When it was filled & held against the wall all it did was drip. Very annoying. We ended up not using it because of this. He's still using the filtered water spicet.

Pros: looks like it would work

Cons: constant dribbling

We have this in our gerbil cage and it works well. Occassionally we have a drip problem but it can always be adjusted to stop.

Pros: It lasts and works well

Cons: none

We put it in a holder and it fit nicely on the tank. Even with the highrise addition. Worked well for gerbils.

Pros: Fit on cage nicely

Cons: none
