Since my cat passed away my slightly younger cat is playing up a bit. She's attacking my mum, crying a lot and seems very restless. Both her fav. things are gone. She's never been alone and always had another cat and now when we're not here she's alone, and the only thing she would ever play with was him or the water bottle lids (which we will no longer give her because of what happened) and she just seemed totally lost. She's being very very clingy to me when I'm here so much so she's keeping me awake at night now. She'll either attack me while I'm asleep, nuzzle my head constantly till I'm awake or sit under the quilt, ontop of me, clawing me for hours. I really don't know what to do with her.
