Instead of shooting those evil dogs and cats invading your homestead with bullets try this..... Get a big supersoaker, one for everyone in family. Get a couple gallons of white vinegar. Fill supersoakers with vinegar, pump up and give test squirts. Next time you see dog/cat/human pump and squirt in the face (eyes and nose) and on the backside as they run away. The vinegar will sting them badly but no permanet damage. They will stink for days and will have to lick off the gross stuff. This will learn them reeaaallll good. The dogs I've done this to have never been back since,but if yours do then I'm sorry, you'll need real bullets.
