What do you do with yours?! We have 3 cats and one large bin that it goes in but it stinks. The trays and bin used to be in the garage with the litter tray so the smell wasn't a problem but we've moved house and the litter tray is in the utility room, so every time we use the bin a smell of cat poo wafts through the house.
I'm registering as a childminder at the moment and the litter tray is a nightmare - the trays were in a double cupboard in the old house so we've modified a kitchen unit for the trays to go in the new house but the older cat refuses to use them and just poos on the floor. I need to make it safe and hygienic for small children running around and do not need to be picking poo up off the floor every morning!
