Isn’t it a great habit for them to “pick up” ?
My girl Juli AND my girl Grace both decide that digging would be a fun new past time for them one day. Juli literally stands with her back feet perched on the edge of her litterbox and flings every last thing out. Have you winessed Pepper doing this? It actually looks so funny you might forgive her for a bit
I have found that Juli and Grace do this near litterbox change time, when they start to get a nice pile of hay/poops in their box. To remedy the situation with Juli, I placed a grate over her litter, and hung a hay rack over her box rather than placing any hay in the box. I fashioned the grate by going to Home Depot and finding these plastic grates that normally go over flourescent office lights. They are this white kind of grate with small squares. I cut them with a pair of wire cutters to get them the right size (be carefull to make it the right size because the edges can be sharp and if its too small Pepper might get a foot stuck between the box edge and the grate and cut herself. This has worked well, and each night any hay or poops on top of the grate I dump into the box and place the grate back on top. Now Juli has nothing to dig
Poor Grace is blind so I haven’t taken her joy of digging away from her!
