Howdy. My name is Andrew McIver. I am the managing member, which means owner, of Avalon Manufacturing LLC and the inventor of the Critter Quitter Vent Shield. I want to welcome you to our blog and hope you will find it useful and interesting. We will be using this blog to post interesting things about vents and roofs, helpful hints on our Critter Quitter Vent Shields, and even some discussions about our friends the squirrels and their importance in our ecology. Check back often and please feel free to contact us with comments, questions, or simply observations. Remember, save your vents, and save the squirrels.
