Hello, anyone with applicable experience with this topic please advise me if you can!! My wife and I just obtained two orange tabbies from the pound about three months ago. We are lifetime cat owners in our forties. I have installed a cat door for them to have their freedom to roam. Now I am looking for ways to discourage the two cats from bringing moles and mice into the house through the pet door!! Our last cat did so only 2-3 times a year, these youngsters are doing so 2-3 times every NIGHT. It MUST be stopped before they graduate to bunnies, birds, and snakes. Please do not waste my time by lecturing me about keeping my cats indoors all the time, or uninstalling my pet door, because you will never convince me to do so. We are quite familiar with the concept of the cat bringing us gifts into our home, but this must be stopped!! I can lock them out at night, but I appeal to YOU, the reader, to provide me with a creative solution!!
