Product Overview

The Kitty Tube Vent Cap and Gasket

This cap is needed to eliminate moisture laden air that can build up under the top lid. This moisture laden air can cause condensation in certain temperature swings. This cap serves the same purpose as the vents on the roof of your own home that expel excessive moisture in the winter and heat in the summer. This vent cap is very important in maintaining a dry interior for your cat. 

*All Kitty Tubes will now include a vent cap and gasket.


NOTE: This cap can be installed on all older model Kitty Tubes and will greatly improve its performance. To install a vent cap on non Generation 3 Kitty Tubes a 1½ inch hole is needed on the top dead center of the lid to install. We recommend using a standard 1½ inch hole saw to make this hole.

    Great product from a great small U.S. business

    The actual kitty tube is a fantastic product that has perfectly sheltered a couple of feral (but very friendly) cats. I contacted the company regarding a small concern with the vent cap and was pleased with the prompt and friendly interaction. This particular vent cap is prone to popping off during very hot weather (otherwise I'd give it 5 stars). The company is aware of the issue and is looking for a potential solution. Gorilla tape is a simple fix; it's not pretty, but it keeps this vital part attached during the heat of the day. Again, great company!

    Vent Cap Addition

    Posted by Nancy Griffin on 29th Nov 2016

    While I've never had any of the problems described in the product description, I felt it best to be proactive and install a vent cap to prevent any such thing. As a single, older woman, I have to say it was quite easy to install. My only recommendation for other petite females, such as myself, is to be sure and hold the drill firmly with both hands. Overall, it took me no more than ten minutes to gather the tools and do the installation.
