petdoor installation

[Mardella]

We have a Homelite Mobile Home circa 1975 and want to install a petdoor in the back door off the kitchen. Does anyone know what the interior of the metal door is? Can we cut through the door to install the petdoor? Any help is appreciated. Thanks.

there is a good chance that the inside of this door is styrofoam. You can cut the door with a jig saw - just drill starter holes at the corners. This is easiest when done with the door removed.

Galen...thanks so much; I'll give it a try!
