Well...what type of set-ups are we talking about? If you have a rack system, use a stone crock bowl...like a dog food dish and use the size deli cup that fits it as an insert...then you just take out the deli cup and clean or replace with new water....If you have a 4'x2'x 2' adult cage then I use the big hard plastic Dog dishes...I bought them at Walmart...they hold well from tipping...although I have one male that seems to have to soak just to go to the bathroom every time...so his bowl is not as full....or else the cage ends up soaked...lol..Hope this helps.
