Even though it's not your land can you cut back some of the brush? Or maybe something distracting like some old CD's or aluminum pie pans that would blow around in the breeze?
Or possibly a motion activated alarm? Something cats would hate.
If you have a harbor freight they have cheap motion driveway alarms. If the cats walk between the sensors it will beep while they are in the sensor area and stop when they leave. You could put them where they cats are sitting. It might make them move elsewhere.
Also, this sounds crazy but I know people in my area that do this. Scent mark the area with human urine. Or if you have a neighbor with a large dog put some dog poop in the area they are hanging out in.
Just brainstorming some ideas.
Our property is bordered by woods. It had been logged out but then brush and small trees grew in. We have bobcats, foxes coyotes and bears. Last year I went is just trimmed it out. The owner doesn't care and it gives predators less places to hide. I have had 2 bobcat attempts on my girls. Once she went after my hen Psycho. Psycho did her freak out thing and ran away. The cat just stood there in shock. Last year it jumped over the stone wall and then 20 chickens freaked out and the cat ran back over the wall.
That's such a good idea!!! Someone gave me an electric hedge trimmer and I reckon that would work. And yes I can. No one lives there and I'm sure I'd be doing them a favor cutting it back a bit as I'm sure they will do it again eventually.
I do have a harbor freight near me and I'll look for that. I do pee around my run quite often but I've heard it disapates quite quickly so not sure if that works.
They are right by my dog run which has worked really well at deterring predators. I believe the bobcat is just trying to feed her babies so she's probably desperate.
I would have been scared, then cracked up laughing if I saw that . I went into farm animals with no clue how to do things in 2019. The predators were at 0 until I guess the rabbit population went down and they've grown desperate.
Thanks for all your help!!!
