Great bottle which the rabbits love. The green spout fixes into the vertical spars of the cage, similar to a bird cage water bottle. I use it in horizontal bars of my rabbits cage. Both ways need an extra support to hold the bottle. I have used string (which won't last long, I know!) I plan to use garden cable ties or a small bungee cord to do this. As I said, excellent bottle, rabbits love it. Only four stars due to the fact I needed to get an additional support of my own. Please supply in future, Zooplus!
Huge. (I bought it for my ferret). The bowl is perfect size for drinking, but if your cage walls are high it might hang to high for a smeller pet.
The bad thing is they didn't include that thingy to hang the bottle to the cage, so i had to think of something how to hang it on the cage... its good now :)
