I too have one who digs for Australia thus covering everything in cat litter
it takes quite along time to acheive this mess but he seems pleased with his work and even shakes his legs of litter as he leave. I have another who doesnt cover, but more air covers
this is he scrapes the wall, the floor etc so just mimics the act but never a grain of litter actually covers anything
he also perches right on the edge of it like an owl to poop - unfortunately he has on occasion been facing the wrong way....
Thankfully my tray is used very infrequently now they prefer the gardens lol
I thought it was trained behaviour from their mother, but maybe its just she didnt bother either?? Once they're older they will take particular exception to having poop on their feet, so if anything they will at least be more careful - she says, hopefully
Very brave to bathe by the way
i value my soft tissue and life far too much
