Leanne is a two month old kitten and she always uses the litter box. At night I always put her in her large cage (contains box bed, litterbox, mini scratch post, cardboard boxes for perching and scratching, and lots of toys.) For the last couple of nights, she's fallen asleep with me in bed, and I haven't put her in her cage. This morning, I woke up to a large poop beside my bed and her scratching the carpet in an attempt to cover it up as she does with litter. Her litterbox was only three feet away (the cage was open). I quickly scolded her and placed her in her litterbox, closing the cage door. Why did she do this? Can anyone explain/prevent this?
