Would it do any good to leave the spotlight on or get a motion sensor light? That wouldn't stop your critters from goin' towards them, but would it keep them from the house?
Or you could get a coyote trap. But you have to put those as far away from your house as possible...no wait, that's a Japanese Beetle trap.
Sorry. I got confused. ;-)
Problem is you have to bait coyote traps with cats and she's only got three of those.
I think if it was on all the time or was automatic, they'd learn to ignore it. They stop and scatter because it's us, and we often yell too. You remember all the issues I had with shooting them. They're still issues... and at this point, we haven't seen them when they party like that... not even eyes. Too much brush and undergrowth.
I talked to the trapper on the phone after the other sightings when they were getting bold. He said he could come out and set traps, but that coyotes can be crafty and hard to trap and it might take a while. Honestly, I still feel that we'll never eliminate them, I just want to keep a good fence between them and the dogs, a good sense of fear in them about letting themselves be seen, and the kittens will either have to learn to stay in the compound or stay within a short sprint of a tree. That's just the way it is.
