"I have raised hamsters for 5 years and will soon have rabbits and cavies too! I bought this bowl around year 3 for my hamsters. I had tried the plastic ones I had tried the lock-on crocks, I had tried almost everything. And I had spent a fortune too. One day I went to my local Petco and saw this bowl on the shelf and figured it was worth a try, i mean nothing else has worked. But this sure did. It was chew proof where as the others were shredded. It was easy to clean, where as the others held soapy residues. It was stylish, where as all the others were bland. This fit all of my needs, and the size choices were great, it worked for my syrians and my dwarfs. Thanks so much for a great product. It is very easy to clean!"
