Right. So a trench and a fence will keep the cats on her property.
Idiots.
I had a neighbor lady once that rightfully complained about my cat pooping in her flower bed next to her porch. I bought some stuff designed to keep cats away. Didn’t work.
She threatened to get a cat cage, catch my cat, and turn it over to Animal Control.
And that’s exactly what she did. I bailed the cat out. Somehow the problem went away. Maybe my cat learned not to trespass over there.
