Also have two cats and am worried about them coming into contact with the woodchuck
Buy a woodchuck beeper it a rig that is battery powered and you stick the tip in the burrow it sends this godawful beeping noise down the burrow and drives them away and you hardly hear it above ground ask you local gardencenter about them-i am sure they can help you
you can try buying either fox urine or coyote urine at a garden center; worked for me but then a family of skunks set of residence.
If the cats use a litter box then try putting some of the used litter in the hole. The smell of a predator will usually cause the groundhog/woodchuck to leave the area.
EASY ANSWER! Take the cats dirty litter, your hair, if the neighbors have dogs.. llect some poo also... Stuff all this stuff down the hole that is closest to your garden then put a big rock over the hole. Usually, woodchucks will be so grossed out by the different smells that they will dig a hole in a different direction and your garden will be out of sight out of mind. As for the cats, well the best way to stop wood chuck hunting is to keep them inside. I had this old TOM years ago, He would hunt woodchucks....limp home with bites the size of silver dollars. Go to the Vets get stitched up and before the stitches were out he was back hunting woodchucks only to get bitten and stitched again, and again, and again, until I neutered the damn fool and kept him in the house!
