So I told ya'll I'm trained in the litter box as well as going outside on the grass right? Well, I went in the litter box as usual today and guess what happens? I lifted up my legs and went on mommy's wallpaper. I guess Mommy never expected me to lift my legs up in the litter box but I did, now, my pee pee did make it in the litter box but it had to go down the wallpaper first....whoopsi..... Sorry Mommy.
