Cat scratching on bedroom door all night
I am in desparate need of help. We have 2 cats and 2 dogs, who've all lived well together for many years. Just in the past two months though, our cat, Lilly, has gotten into the bad habit of waking us up at all hours of the night by putting her paws under the bedroom doors (we have 2 doors to the room) and jiggling the door, scratching at the door, etc. We have tried numerous things to stop this behavior and nothing is working, and we are getting no sleep.
We have tried feeding her before bed (she used to only eat once in the morning, but now gets a bedtime snack); we've tried squirting her w/water and even putting her in the shower when she does it, that hasn't stopped her; we've tried locking her in another room, but she gets mad and urinates and poops in that room; we've tried putting that "cat-off" spray on the bedroom doors, still doesn't deter her. Nothing is working. I've tried ignoring the behavior, but it just gets so loud and I finally give in and either get up and feed her or put her in a room, but I know both of these things are etiher reinforcing her or making her mad so she acts out(being locked in a room).
I am at my wit's end. Lilly is a very affectionate, sweet kitty, and this has only started over the past 2 months but is getting worse. We've never let her sleep in our bed except occasionally, b/c the dogs sleep in the room w/us. Other than this, her behavior is fine. But she does have hairball problems a lot, and we treat that as directed by our vet, but lately she seems to not be able to get her hairballs up as easily and its causing her tummy to hurt so she doesn't always eat all her food at each feeding. She is only 8 yrs old.
Any advice would be appreciated!
