Cat puzzles (Brightwood Park/Petworth DC)

A highlight of my cat’s day is playing with a toy that requires him to nudge, bat, slide, or jiggle something that opens to reveal a treat inside. I have 3, plus a Kong ball, all of which he enjoys, but he could use more. Before I buy a new plastic thing, thought I’d ask if anyone has any they don’t need. Of course I’d pick up. Many thanks.
