Do you mean those ultrasonic cat scarers? I only found them to work on *some* cats anyway, overall I didn’t find them that effective. You would be better providing a cat-proof feeding station for the hogs (lots of pics ideas and designs round this forum) so that the pesky things can’t steal the hedgehog food.
Cats don’t particularly bother hogs otherwise although I do just detest having the blasted things come in my garden anyway. I saw one touch a hog once and let”s just say it didn’t try doing that again!
After years of trying I’ve never found a proper and effective way of keeping cats away. However my hogs are perfectly happy with their cat-proof diner!
By the way, re hedgehogs, welcome to your new addiction! You have now joined our Hogaholic support group.
