all 4 of my cat's are litter trained. however, Sparkle & Glamorous stopped using it (as they were going outside to do it). i have now decided to have all my cat's as indoor cat's, & was wondering will they go back to using it straight away with no help?
also, how many litter tray's would you suggest for 4 cat's?
