Hi there, new to here but looking for advice. Our poor boy had to be pts last week and one of our other cats is really not coping. She is prowling the house and outside looking for him. She was never affectionate with me or DH but loved having cuddles with our boy. She has become a bit more clingy but shouts all day and all night. Am grieving badly myself but more worried about how to help her with her grief. Any ideas?
