My backyard abuts a golf courses 6th tee. I have a 6ft tall wrought iron fence separating my property from the golf course. I have a patio area that also has a shorter wrought iron fence separating it from my swimming pool and the rest of the backyard. Ive got 4 dogs that can access the patio area. Unfortunately I also have a problem with numerous cats in the neighborhood that wander into my backyard and drive the dogs crazy. Ive let the dogs out to chase them but the cats always get away. What about an airsoft rifle on full auto? Would I be able to drive off the cats without killing them? The maximum range would be about 60-70 feet. I cant and dont want to use a pellet gun because I dont want to hurt the critters and the golfers on the tee can see me. Ive seen those shorty AK-47s and M-16s that run on batteries and fire the airsoft pellets on full auto. I have also seen some much more expensive full-scale metal airsoft guns but I dont want to go that route mainly because of their appearance and the golfers who would soon be on the phone to the police. Im talking about those short little guns that are less than about $30.00 everywhere. Would one of these be effective for the 60 ft or so I need? Would they be accurate enough to bother the cats? Are they very loud? The worst I want to do is to bonk them on the head and annoy them enough to get out of my backyard without having to let the dogs loose each time. I have a Walther P-22 with a legal suppressor but thats out of the question for this urban environment. Your opinions? Thanks in advance.
