So my cat has been pooping in the litter box with the same litter inside all of her life. Now she is deciding to poop in the hallway, away from her litter box. I will put her in front of the litter box, and even put her in the litter box (well shove her in is more like it) and she'll just pop out and run away from it and continue to defecate on the said carpet. She'd poop on the old carpet and now is pooping on the new carpet that has been put in a few weeks ago. I thought this was her way of acting out when the older cat would come down and share the house with her. Now she'll do it even when the older cat isn't around. She doesn't even cover it up she'll just leave it there. Another note, this might help too, she has recently been lying down and rubbing herself (that's what it seems like) on anything and everything lately. Please help, I'm at my wits end and don't know what to do.
