Hey guys, just joined this site and you all seem like a friendly bunch. About 3 weeks ago our housekeepers cat had her first litter of 3 kittens. She's an outdoor cat so she does her business outside but I'm raising her kittens to be indoor cats so they can find good homes. Since they're almost 4 weeks old I decided it was time to start litter training them so I placed a shoebox lined with plastic in their pen and filled it with some homemade cat litter. Problem is, they keep wrestling and sleeping in it! I went to check on them in the morning and they kicked half the litter out. I played with them till they were tired and put them in their bedding on the other side of the pen. But they crawled back to the litterbox and huddled in it to go to sleep. Is this okay? Will they eventually learn how to use it? Their mum can't teach em coz she's never seen a litterbox in her life. I try to stimulate their bowels but they walk/squirm away. Any advice?
