The trap needed a little adjustments b/c if we barely bumped the outside it would close. We tested it with our little pug whose's a pig at heart. She eagerly ran in it everytime to get the bisqit after she figured out she couldn't get the treat thru the sides. We were dying lauging in the garage..hahaha. Not sure how much a coon weighs but Fergie is 8 pounds and she didn't have to hit the lever that much for it to close. Really hoping we catch something tonight!!
