Invented circa 1992 by Allen Gross. It was intended to be a more humane rattrap. Instead of killing the rats, it flung them up to 50 feet into a cage or bucket. The dazed, but still living, rodents could then be either turned over to authorities or released into the wild. Noted Gross, “I didn’t want the (rodents) squashed or turned into meatloaf.”

Turns out this wasn't the first rat-flinging trap to be invented. Back in 1912, a similar device debuted, also called the Ratapult. Though it wasn't intended to be in any way humane:
A metal arm, operated by a powerful spiral spring, is released, and, passing through a slot in the cavelike compartment in the manner of a catapult, it strikes the unfortunate rodent with a blow of sufficient force to break every bone in its body and hurl the carcass at least fifteen feet away from the trap, far enough away so other rats will not be warned against the trap.

Tough way to earn a living.
This 1908 news story may have inspired Roald Dahl's short story
"The Ratcatcher" (first published in 1953 in
Someone Like You). Even if Dahl hadn't seen this exact news piece, he must have heard stories (urban legends) about rat catchers doing this.

A man named Malone, who was fined at Northampton, for breaking hotel windows, was said to earn his living by going from place to place exhibiting freshly-caught rats. These he tethered to a table with string, giving them a certain latitude, and then, with his hands tied tightly behind him, he fought and killed a rat with his teeth. Nine times out of ten he was said to succeed, but frequently the rat bit him severely.

I wonder if this was the tune he played.
The
July 14, 1952 issue of Life had a photo feature about a contest sponsored by the city of Hammond, Ind., in which schoolchildren were asked to design a better rattrap. The challenge apparently released the inner sadist in some of the kids.
Arnold Knopf's trap: a weight falls, releasing a crossbow which shoots an arrow into the rat's back.
Jim Olsen's contribution: after the rat trips a trigger, a weight falls, jerking a noose tight around the rat's neck.
Steve Miller and Ed Cox designed a rat guillotine that included a basket to catch the rat's head.
