NOTE: The Big Cat Door can be installed in most doors and walls. Installation in thinner or thicker

applications may not require the plastic core covers and tunnel support. Additional skills, tools and materials

(such as wood framing and hardware) may be required. It is not possible to cut holes in tempered or double

pane glass except at the time of manufacture. Consult a professional glazier or glass manufacturer to install

the pet door in a glass door or window.
