We would never yell at her or do anything to spook her! We just clean it up and move on, we don't want to make a big deal of it. We cleaned up the area with pet stain remover and she hasn't peed in the same spot again. She also peed in her crate yesterday, so I also cleaned her crate with it as well to get rid of the scent.
We have been taking her for a 15 minute walk every morning where she pees/poops, so I think she was just not on a strict schedule yet. The group we adopted her from took her to the vet and go an all clear, though we are taking her again at the end of October with a poop sample. I think she is still just getting used to our place, so hopefully it won't be reoccuring!
I think for her it is just marking, her foster family told us she did that a couple of times too. And, oh that is so cool! Maybe we can teach our grey the same thing!
I love the idea of throwing them a party, haha! We do give her treats after she pees/poops, and shower her with affection afterwards! I think it was because we were still in the transition phase of coming from the foster home.
Congrats on your two greys!!!!
