I live in an area where we cannot discharge firearms within the city limits. However, we have a lot of coyotes, and they are getting more confident and brazen about being around us humans in our neighborhood. Pets end up missing. I am taking no chances with my small grandchildren when they visit. I am told we can use air guns - pellet rifles/pistols - to scare the coyotes away. I am unfamiliar with air guns. Any thoughts about which air gun - rifle or pistol - would be suitable for this purpose.
