My cat Hazel, (1 YO, Female) has been peeing on my sister’s bed nonstop. She is spayed and didn’t use to do this but she’s been on a new blanket at least 7x in one week. We even put a new litter box in the room but she looks at it and doesn’t use it. I spray non-marking spray but it doesn’t work. My sister wants to give her to the shelter at this point and I really don’t know what to do. I don’t know if this helps but Hazel also really doesn’t like humans, she runs away whenever we get near her. Which I don’t understand because she was born in this house and has 3 other siblings. Does anyone have any advice?
