So I started this thread http://www.thecatsite.com/t/246465/i-nearly-stepped-on-her about a kitten that I am currently fostering. She is 6wks old and doesn't seem to know about litterbox behavior. Will she pick this up on her own if she is caged with a litterbox or do I have to encourage her? Right now she pees on the towel that I provide for her to sleep on.
