I use the Home Depot tubs as well. Clean every 3 days like clock work. Food hoppers are always kept full. Not a single chew mark on any of the tubs.

I also have a different rack I use the jumbo petmate litter pans on. Again clean every 3 days and keep hoppers full. No chewing on these tubs either.

All water bottles are changed every other day and topped off on off days.

My tubs are always full of rats as I don't pull pregnant females.
