Sarebear yu do have a clever kitty!

The cat sleeps on my bed. Her litter is in our ensuite under a bench. The bedroom and ensuit are HUGE. She goes ot the toilet (both no 1&2) in the cnr of the dining room on floor boards which are startng to warp from the moisture becuase sometimes I just don't get to it instantly. She will also go around hte litter tray and occasionally in it.
Up until a few mths ago she was fine and always went in the tray. I have been using htat brand of litter for about 3 yrs.
