We actually had a couple in town that had an alpaca. The neighborhood kids loved it & the couple took their pet for regular walks.But you can't deny that seeing a llama as a flock protector in a neighborhood would be the most awesome thing ever!
As for me, I have the solar, red, blinky, LED lights & talk radio playing all night. I told my next door neighbor about the fox & the radio. She was relieved to know about the radio. She laughed & said that she kept hearing "little voices" when she went out back with her recycling.
I also read that male urine could be a fox deterrent, so I've been letting my dogs out back. They happily mark their territory, but they're neutered so I do not know if that will still have the desired effect. As a back-up plan, I asked DS & DH to help out as well.
