[cypher]

Some Russian hams will pee in the wheel but a healthy hybrid pees so little it shouldn't really be a problem, my Chinese all pee in the wheel but I find that cleaning once .a week is adequate, if you clean too often they just tend to do it more.
I've found that most of my hybrids will be pee in a small tray with chinchilla sand if it's in the house (if the house is big enough) or close to the nest.
