One night, a friend called me in a panic. She lives in town, but on a rather large piece of property that is surrounded by woods. She has a lot of wildlife that take advantage of her land, and they usually don't bother her. On a normal day she sees deer, bunnies, birds of all types, and the occasional opossum. She enjoys watching
them at times, what she didn’t like was when she discovered that a raccoon was walking in through her kitchen. Pet doors can leave anybody open to this problem.
My friend had been noticing that some things were missing, and that food was going fast. She has a cat, which is the very reason that she has pet doors, and she has had her for a while. She knows how much the cat eats, and noticed that the food was getting eaten at almost twice as fast as usual. Other things were also happening that she could not explain. Finally, she saw that a raccoon had come in through her pet doors on her back porch and back door and was eating everything in sight. The mystery was solved.
She decided right then that she had to close up her pet doors. Having a raccoon coming in each night was not something she wanted. Most people wouldn't. The problem was that now she had to worry about her cat getting in and out of the house, and would now have to have a litter box, something that she had avoided up until that point. She called someone to come board up the pet doors. For a few nights she heard the raccoon scratching at the door, but after a few days it moved on elsewhere, much to her relief.
If you have the same problem with your pet doors, you may have to think about where they are located, where you live, and how big the opening is. If you can help it, you only want something as big as your pet using it. That won’t stop all other animals, but it can keep the larger ones from coming in for a late night snack. You may also want to have a pet door on your garage and have some food put in there for your pet during the night. That way, if something else is coming in through the door made for pets, they are only getting into one area, and not into your house.
