Tomahawk Live TrapModel TD10 Trap Divider for 10" Wide and Smaller Traps and Cages

What are the dimensions? 14x12 as stated by amazon or 18x9 as a review stated? I need one to fit a 10 inch wide trap.

What are the dimensions?

This will work for most cat traps? It's 12" wide and 14" tall?

Has anyone encountered an instance of a feral pushing past this divider and escaping the trap?
