Question from my sister--- Anyone have ideas on how to encourage a kitten not to sleep in her litterbox? She is being "crated" at night (big dog crate) until she is old enough to be safe alone at night loose in the house, and she has a really nice soft fleece-covered crate pad but she chooses to sleep inside her litterbox instead! I suggested getting a nice bed so she got the crate pad but this morning she found the kitten sleeping in the litterbox again...
