I understand you very well, they are very skillful when they are hungry and they help also each other. I had 3 cases when a racoon was liberated out of the trap by the help of his comrades who working on the trapdoor from outside until the other was able to open from inside. This ended when I perfect the traps, btw.

"Names for the species include the common raccoon,[6] North American raccoon,[7] and northern raccoon,[8] The word "raccoon" was adopted into English from the native Powhatan term meaning “animal that scratches with its hands”, as used in the Colony of Virginia. Its Latin name means “before-dog washer".[9] It was recorded on John Smith's list of Powhatan words as aroughcun, and on that of William Strachey as arathkone.[10] It has also been identified as a reflex of a Proto-Algonquian root ahrah-koon-em, meaning "[the] one who rubs, scrubs and scratches with its hands".[11] The word is sometimes spelled as racoon."

I only mean he is thinking most times with his stomach and if there is something to eat he goes into the trap like the members of his family the days before.
In an open standing trap a fox would not go closer than 10 meter.
