I am perfectly willing to be told AIBU!
We own three of the four boundary fences around our property (we get the ugly side!).
Our next door neighbour has installed a row of spikes on the top of our boundary fence. This is presumably to stop the cat.
On one hand, I sort of understand this, he is very proud of his garden. On the other hand, we have a very elderly, non-hunting, cat who is just about spry enough to get over a fence and enjoys going outside.
Spikes also seem cool to the wildlife, like birds.
AIBU to think the neighbour shouldn't install spikes on our fence without asking us?
