Every night my DH has a 'nice bath'. He shuts the door so that his cat doesn't sit there constantly meowing at him whilst in the bath. So instead she does this to me 
. Put her outside & she scratches non stop at the cat flap & same applies to kitchen/kitchen door. Either way she pisses me off. She is not my cat & don't particularly like her.
Would it be unreasonable to let her upstairs to bother him???
She is not even mine - wtf am I sat here listening to her?????
