Don't shoot the dog with a BB. Leave something tasty loaded with laxatives outside when you see him about. Hopefully in the late evening so he can crap in their home."... the property owner informed me that one of her 3 cats had been shot."
Even the dog that sometimes runs and is vicious would only get shot with my bebe gun, just enough for a vet bill.
I would NEVER shoot a cat!!!
How about using a .12 ga shotgun on night patrol ?Moth balls will work but you have to use enough that you will smell them 10’ from building. Ag used a stinky insecticide to stop them from eating the seed but they still use whatever for nesting material. Only sure way is poison the beggars. Maybe heating the building to 70 degrees and turning snakes loose might do it. I’d use poison.....just sayin....
