Any advice on how to stop this?
I have a 5yo female cat. My lovely neighbour has a 1 year old male cat. We live in London, where many homes have small back yards and there are many cats. Ever since her cat reached adulthood he's been trying to claim our house and backyard as his territory. We have a sureflap microchip cat flap. He stares through the transparent flap at all hours. At night he batters himself against the flap trying to get in. (He has his own cat flap on his own home and he isn't locked out.)
Last night I was awoken by the noise at 4.39am and I listened to the continuous bangs and slaps until he was scared away by a neighbour at 5.56am. He really did headbutt our cat flap for nearly an hour and a half. (I have chased him away on previous nights but he's back within 5 mins.) My poor cat hardly goes out unaccompanied any more and has entirely given up hunting.
I could sleep wearing ear defenders.
Or i could ask the neighbour to lock him in at nights. (But he's such an energetic cat he creates a rumpus in her home and she gets no sleep if she does that.)
I also wonder how robust the cat flap is and how long it will last under such a battering.
Is there anything we can do to get this young hooligan to be peaceable at nightime?
