The neighbours have rigged a system of poles and netting obviously designed to keep the furry delinquents out of their garden. That's fine, although I was a little concerned about the rows of pointy bamboo sticks that appeared originally. It's since been redesigned to look a little less like something that was intended to impale my cats.
I have no doubt in my cats' abilities to circumvent their defences. These guys can get to the top of a 12 foot bookcase with minimum effort.
This morning I discovered that they hadn't in fact circumvented the system.
They'd pulled it down.
In the half an hour they'd been out after breakfast. It took the neighbours 3 times that time to build it.
