Good way to keep cats/animals from scratching on a door

noise reductionpet-proofing

My girlfriend doesn't like sleeping with my two cats in the room at night, so I've started keeping the door to my bedroom closed. Unfortunately, however, they meow and scratch all night long.

Is there some way to keep them from scratching, or to damper down the noise so we can sleep soundly?

I have hardwood floors, and I'm sure this doesn't help with the acoustic amplification of the sound.

Best Answer

you can use an automated air jet/spray that activates when the cat comes close to the door
