I have been having problems with feral cats this year. I first noticed them shortly after I moved into this house about a year ago, but didn’t have any trouble until this spring when I came home from the hospital. One of the ferals had a litter of kittens in the neighbor’s densely wooded lot, and they’d come into my yard to play. The first problem I had was the feral cats raided a wren nest on my porch and at least ate the babies. Not sure if they got the adults or not.
