Funny, brings back memories of my encounter with raccoon. I made mistake of rescuing a baby raccon after its Mother was road kill and the little baby kept running into road to be next to dead Mother, pretty sad, so I let my emotions get the most and saved it from death. Took it home, as an animal lover, just wanted to give it a fair chance, so fed it until it was big enough to go out on its own, but didn't. lol
Long story short, I couldn't get rid of him for they are always looking for the easiest meal, and I was it. He would break into house, pulling screens off windows and doors, amazing how cunning they are when it comes to getting free food. I ended up taking him deep into the woods for he wouldn't leave, actually would sleep up on my roof at night as safe as it was and easy not to leave his food source.
So lesson learned, get rid of raccoon if you can, just buy a safe trap and catch him, then take him to woods a couple miles away and your problem is over. Easy to catch as they will eat just about anything, so bait your trap with maple syrup which was my raccoons favorite snack. lol A more expensive option is to get an electronic pet door which activates from reciever on pets collar, works great and only opens for your pet. By the way, raccoons stink to high heaven if they get into your home and start marking their territory as food source, so if you notice a smell, try Green-Homes.com air odor purifier, worked great in my home.
Success to all,
