My ndn has historically been a challenge to live in harmony with. I have two cats who frequently climb the dividing fence (her fence) and go into her garden. They clearly see this as an extension of our garden. Other neighbourhood cats also move through all the gardens.
The ndn has nailed strips of sharp plastic spikes along the fence, the spikes are sharp enough to draw blood if I push my hand down on them. One cat was limping last night. I am so angry that she would want to try to hurt any animal , there are two stray Tom's who live in the area which wouldn't be able to see a vet easily if injured. Is there anything I can do? For context she is a lady who lives alone, no partner/ children and generally intolerant of normal neighbourhood activity.
