Maisie has been driving me crazy. Every morning she wakes me up by scraping her claws against the litter box for at least 30 minutes. I don't want to yell at her or shoo her from the box, but the sound is so irritating! Both boxes get scooped daily, they are both full of litter and I don't know what to do to make her stop. I live in a studio apartment so I can't move the the boxes anywhere else.
