My boyfriend's cat's been acting bizzarely over the last few days as well. She's been really clingy ever since we got back from our holidays in Feb, which we just reckoned was her missing us (she's never been on her own for that long before), but just this week she's got much worse - she howls whenever Lee's not in the room, and starts scratching the doorframes if she knows he's behind a door that she can't open. She's also started mewing and scratching at any doors that she can't get into, even the cupboards, and the bathroom, which she's never been allowed in.
Last night we had friends over, and afterwards, she would not leave us alone - crawling over us, miaowing and pawing us whilst we're trying to sleep. When we put her out of the room, she started howling and scratching again (there's now a massive gouge out of the skirting.

). It's driving us up the wall, any advice would be helpful!
