The Critter Quitter allows quick and easy repair of damaged plumbing vents, to keep frogs, rodents and other animals out of toilets and plumbing. It requires no modification to the existing flashing, so it can also be used on new vents. The patent-pending design redirects rainwater into the vent and out the house drain, thus keeping the area between the outside of the pipe and the damaged flashing from becoming wet. This stops further leakage into the plywood decking. Available in three sizes, its outside shell protects the vent from squirrels.
