I have four DPs with caps spread out across the wooded section of a customer's backyard. They are baited with dry cat food with a little bacon grease for attractant. The first check I caught one raccoon and the other traps were untouched. On todays check, three of four caps were removed, some bait gone, but not catches. What animal besides a raccoon could/would do this? I was thinking skunk or possum but did not think they had the dexterity to do this.

Thanks to the knowledge base.

Pack rats?

I doubt pack rats. I went to caps this year because I’m over run with them and fought them constantly last year. Either cleaning my DPs out or getting head caught. Despite a lot of pack rat tracks I never had one get the cap off. They licked the trailing scent off but didn’t get the caps off.

Sounds like squirrels to me.

Some BIG possums can get them off. It could be curious coon which aren’t hungry

I agree and even a skunk. At this point go to foot hold or cage. This time of year try some kind of gland lure. These guys can tell you what to try.

With bacon grease I wouldn't rule out dogs, cats, possum, skunk, coon, fox, and squirrel. I use fryer oil and have seen them all spend a considerable amount of time messing with DPs. Set up a camera and let us know.
