I also have this box. We call it the Magic box, lol. Have a diabetic kitty that was having accidents. He loves this thing. Not one accident since we got it for him.
Good luck with the baby.
Oh, maybe if I put some litter in it, Gabrielle will start to use it....maybe her sister bugs her, you know wanting to know what she is doing....pestering her...will give it a try and if it doesn’t work then back to kitty condo.
