My husband and I put a smooth, flawless coat of epoxy on our garage floor.
Then we lowered the overhead door, leaving it high enough that it wouldn't touch the wet floor but low enough that the cat couldn't squeeze in under it.
The next morning I peeked into the garage and my eyes grew to the size of dinner plates!
We didn't keep the cat out of the garage; we kept her in - all night!
(She must have been hiding on top of the rafters.)
It's a goof we're unlikely to forget; hundreds of little paw prints across the floor's mirror finish remind us every day.
