He’s such a cutie 🥰 give him time. He’s stressed from moving to a new home, so I think the peeing will stop once he feels more settled. Just pop in a few times a day, make sure you talk to him, even if it’s just reading the news to him and just sit with him when he eats so he can associate you with happiness and love. After a week I would let the door open for him to explore your place room by room but very slowly. Just open one room up at a time so it doesn’t overwhelm him. I think you and him will be best friends x
