So I went to PetSmart and found a Lixit Dog Carrier Cage Crock...this thing is basically a clamp on water dish for dog cages....I thought this would work well with a plastic tub....I thought about some people having problems with their snakes turning over the water dish...and this is how it turned out...It works well, but it does require a little bit of work...

















The bowl just slides in and you turn it to secure it..I guarantee no snake will knock that off....it was about 6 bucks...that's about the price you pay for a good solid dog dish...

What do you guys think?
