My husband is in the prosses of being diagnosed with Parkinson's, our cat has been very clingy lately. She normally is the type of cat that only wants to be bothered with when she wants you to touch her, but the past few weeks she has bee very clingy with just him. Once in a while she will lay on me when I'm laying on the couch but she has to be on him all the time. He is getting very annoyed with it, she wants to lay on him when he is in his chair and when he's laying on the couch. Could she be doing this because he is stick. It is starting to weird my husband out he says.
