Good old InventorSpot has discovered US patent 4150505, the bird trap and cat feeder. Why buy your cat food when you can trick innocent birds to enter your trap and become kitty’s dinner?
I don’t imagine most cats would actually be that into this idea though. They seem to like hunting, and not fish in a barrel style.
Aside from that, it seems exceptionally unlikely that a bird would just sit there while the trap started opening. They have these crazy things, they’re called wings.
If a bird did manage to get caught, I would be worried it was sick -and thus, I certainly would NOT want my pet eating it.
All over, this has “Stupidest Products Ever” written all over it.
