Megazorb, with hay in one corner. I dont use hay all over so then I can spot-clean daily all the wet stuff and droppings, then fully clean every few days.
In the past I've used :
newspaper under other litter but it takes longer to line the trays, and then he dug it up and ate it :roll: newspaper on its own under hay wasnt absorbant enough and again it got eaten.
Shavings, STINK TO HIGH HEAVEN and also bad for their health.
Woodpellets, very absorbant but smelly and he got wet feet. edit - wet feet if I didnt use hay.
Carefresh, not as absorbant as megazorb and smells a bit more, also WAY more expensive.
