Tracey, with Lizzie and Robbie I bought a stack of thin aluminum baking pans - they were 2 for 88 cents at Wal-Mart. I used small amount of litter, scooped often during the day and threw away the whole pan each day. Easier than trying to scrub the box. I also like QSA's idea of rotating pans and then scrubbing/soaking one and using the other. I do use Lysol but rinse VERY well afterwards. I find bleach so hard to get off with water.

Maybe keep a hand vac or small whisk broom (what I use) and pan for scattered litter control.

Sorry but I don't know about the white flaky patches or what they could be. Please let us know what the vet says, ok? I think I would start using tinactin anyway. I also used this on Liz and Rob.
