Back when I had a cat and a dog, they were firm friends He was a large dog without being massive. The cat tried to scratch his way through the door, and then the dog picked up the project. Difference is, he almost succeeded. I want to fill in the missing wood (shown below) with something like wood putty, but @zacharymarkson doesn’t think wood putty would work, so does anyone have any suggestions as to what might work? It isn’t worth replacing the door over.
I am also having a brain fart. What is the trowel called that is used to smooth spackling on drywall?
