trust me BB guns work for conditioning. I absolutely hate cats but one day a little gray and white one showed up at our house and to make a long sotry short we adopted him. Hes an outside cat and one night i heard screaming out my window. I grab my bb gun( i was about 10 then.) and look out my window to see a big black cat beating the crap out of my cat. So i pumped the gun 20 times(i had heard on tv if you pump it 20 times it will be as powerful has a shot gun bb haha so of course thats what i did) and shot it. Haha the dang thing flew about 5 feet in the air and i never saw it again. Thats what it gets for messing with my cat who was the runt of the litter.
