Thank you! I figured it might be a long shot, but worth asking.

I’m not sure if this is the right place for this, but I don’t know where else to look or what to attempt to research (if someone could even give me some search terms that would be cool, or a different sub to ask this).

We keep our French door open a couple of inches for the cats to go in and out to the patio all day. In the wintertime, this obviously makes the room cold and drives up our electric bill.

Is there anything I can use to cover the gap between the doors (and at the top) and leave a cat-sized hole at the bottom?

This is what it looks like

Considerations:

-We rent, so we can’t make any permanent alterations

-I’ve tried covering the whole of the doors with a curtain, but it’s the only natural light in the living area

-it would have to be somewhat removable so we can close the doors

Happy to provide more photos or additional info. Thank you!
