Temporarily block chimney in fireplace idea needed - kitten problem!

TripleH

Yes, when we moved intobour last rental, my wire put our 4 cats in what was our bedroom. No sooner had she let the last out their carrier than the kitten was up the chimney (fortunately a Maine Coon who did a bit of a sweep up there) and she retrieved her by the tail.

We put a board (fibreboard? the board backing in picture frames) over the fireplace and our chest of drawers in front.

Fixed the issue until we moved out when our eldest Burmese repeated but didn't get as far up.
