Question
Some kind of animal is digging in the mulch areas in my flower bed and in an area that has no plants but is covered with mulch and somewhat shaded from Maple and Beach trees. The mulch is all pushed around and just dug deep enough to maybe uncover dew worms. We have a sprinkler system and it seems to just dig where it is damp thus making me think it is after dew worms. It is also eating my Hosta plants.  I thought it was deer when I first saw the Hosta plants being eaten but I do not see any deer tracks.  They are not digging holes like a mole would.  A friend wondered if it would be a skunk or a badger?
It is right infront of my garage doors just off our drive way and I have a small dog and two cats I am worried about them tangling. We have lots of dense woods on that side of our lot.  I am from Sothern Indiana.  Any suggestions?

Answer
First, your cats shouldn't be allowed to roam freely outdoors. Cats are a major environmental threat due to their incredible predation activities. The second reason is, as you stated, everytime, the cats are out wandering around, you don't know what they have come into contact with. Dogs tend to be different in that they aren't as efficient predators and leash laws tend to be more strictly enforced. We have information on the damage caused by cats at http://icwdm.org

As for which animal is digging around your plants. tough to say as you didn't give a lot of information, ie. measuremebnt of holes, etc.  I doubt badgers as they dig big holes. I am thinking skunks or squirrels. Moles don't dig holes. They are burrowers so your problem isn't moles as you already know.  I am wondering if you have two different problems. One from an animal grubbing and another eating the plants, like voles.

Again details can be learned at http://icwdm.org  click solutions then animal damage id.  There will be a key there on identifying the problem.
