There are many water bottles that are for sale that have a slow lead, which drives us crazy. I would have to say that this bottle is different. I have not had a problem with it leaking. I also bought the chew guard since I have a chewer!

Pros: no leaks

Cons: none

i tried these for my birds a long time agoand found they did not like them. birds would rather dip and swallow then lick. i did use them for my g pigs and mice and they were great

Pros: good for small critters

Cons: not so good for birds

I like these but they need chew guards or something because my glider eats right through them.

Pros: works great different sizes pets love them easy to put up and take down

Cons: my glider chews holes through them, we had to buy glass ones.
