Not Chew proof

I bought this product for my two rats.
Not only did it leak, but they chewed right the it less the the days.
I will not buy this product again, instead I will switch to a water bowl.

I had one of these I the cage for my Guinea pig, I found this more effective than a water dish because the dish would always end up tipped over or would get shavings in it. This water bottle lasted quite a while and is a lot cleaner than using a dish.

Ok so this thing works about 75% of the time, which is much better than a water dish in any small animal cage which will disappoint you 100% of the time. This isn't to say that this product is anything to write home about. True, it is absolutely chew proof, as demonstrated by my rats thorough testing, glass cannot be chewed through. However, those goofy springs that you have to wrap around the bottle to keep it padlocked to the cage make you want to throw your head into a wall. They're so fidgety I just end up strapping them on randomly and hoping a glass bottle wouldn't be smashing onto my hardwood floor in the middle of the night.

The weird little duck you see in the bottle sure is cute, so long as you use tweezers to remove it as soon as you buy it. The thing is prone to growing mold. Mold ain't cute. Overall, get a top fill one if such a thing is available to you, but if you cant and you enjoy fidgety springs and ugly ducks, I'll just conclude that you didn't necessarily make the WRONG choice, just not the best one.
