Oh Deb! That must've been awful for the people who had the snake and the coon come inside!! Everyyear we have baby coons in the hollow tree in our front yard, so a flap would be out of the question for me too!!
And about the screens....I wondered if anyone else had that problem, my husband bought all new screens for our giant picture windows that are in the living and dining rooms. He bought them last spring, and since then, they have holes all over them, because their is a brick ledge all around the front of the house...the house has brick from the windows to the ground, and the cats sit on the ledge constantly, which is okay, except they like to climb the screens, and hang from them....I tried using a squirt bottle on them, whenever I caught them doing it, but it hasn't helped...they have a mind of their own...lol
My husband is realy mad, though and threatened to get rid of the cats, but I promised him i would buy new screens this spring, with my own money, so he would calm down.
