my god angela, your neighbour sounds horrendous, it is annoying but not worth causing serious harm!!
I've got a really scaredy cat, she only poops in my garden, I'm glad tho, I've got lovely neighbours and would hate that to change. She goes next door but their rabbit chases her back to mine again - embarrassing.
In the past I have found that it is only strong smells that put them off, pepper, garlic, chopped onions etc not nice to sit with that aroma tho
