Electronic | Automatic | Motorized | Magnetic Pet Doors
You understand the importance of a pet door but you have stray cats coming around spraying, or you have wild animals that might try to break in for food, or you have a cat--or a baby!-- that you want to keep in while you let the dog out, or your pet is so arthritic or handicapped that he just can't manage his old pet door. Maybe you'd just feel more secure without an unlocked dog door. What to do?
The answer, of course, is to get an electronic pet door - an electronic, magnetic, rfid chip or even motorized dog door or cat door. Pay close attention to measuring for size as always. But also think about power source, spare collar keys, locking mechanism and opening method. They'll all play a role in the success of your choice.
