My neighbours have two Bengal cats. They are very beautiful, very affectionate but INCREDIBLY noisy and they have no boundaries at all.
We cannot open a window or door because one or both of them will immediately run in and start roaming around, leaping on surfaces and rolling around. They miaow loudly and (seemingly) incessantly, and for no discernable reason. One of them has taken to killing things and presenting the offerings to me. The other has started using our entire place as an exercise circuit, which involves energetic leaping off roofs and through windows.
My two elder daughters adore them, whereas my youngest and very docile black cat are less keen. I know, they are cats... They can't be told what to do... But they are driving me a bit crazy! They are everywhere, all the time! What can be done?
