my cat use do that but he not do it now as i kept sayin thats dirty&u have clean litter tray there but hes ok now.but i find that they can be bit fussy when want loo cos if its not 100%clean they dont use litter tray&do it on floor or next to u litter tray.do test&see if any beter or worser.

so i would say per cat u need litter trays for?
i only have one cat&he fuzzy&madiey&dosent like me leaving him cos he crys non stop if he not on my lap&he hates goin out cos he crys sraight away as hes goes stright out side.
