Beats the heck out of my feeble attempts, using a radio-controlled model tank as *bait* to lure the cats into the range of one of these....
yeah that is what I referring too when I said sprinkler scarecrow in my post !
bad part is I installed that thing one afternoon and then got called out later and when I came home 12 hours later and tired as I was walking up the sidewalk past the flower bed that thing went off on me !!! Scared the bejesus out of me !
Thought for sure I was got by something deadly in the dark........1911A1 was out and 1.5 pounds was on a three pound trigger when I felt the sprinkler hitting me again !
Not for the faint of heart ......LOL !
