It’s a bit too pricey plus it means ndn, who we don’t like, could get away with not repairing their shabby fence & use ours.
I could spray paint “I never moaned about all my cats UTI’s from your cat coming in my house to finish the gourmet off” on their side of a concrete one though. It might affect the boundary though if I fence their side.
Open to a retired queen too if one came up.
