Unfortunately we live in a really small apartment and we can't really put her anywhere while we're not with her, the bathroom is inconveniently shaped so we can't fit her litterbox in there (we've tried putting it in the bathtub but she's too scared of the tub to hop in there to use the litterbox and just poops on our mat instead), and the only other alternative is the bedroom -and we don't really want her in there, either. We've tried putting things on the couch to protect it but she just pulls it off or digs her way underneath no matter how well we tuck it in and around it. She's like some sort of houdini. She is super smart and we love her for it, but it's kind of frustrating sometimes, haha....
I guess I'll have to try a spray and figure something else out later if it stops working.
Thanks anyway though, I appreciate it!
