I guess this what happens when rats aren't provided with cute toy cars and taught how to chill-out...They go full Hannibal Lector. Though their victims are poisonous pests, so I suppose it's more Dexter
Scientists say native rodents in Western Australia have discovered how to kill and eat parts of the poisonous pests

Australian water rats have learned how to kill cane toads, eat their hearts and carve out their organs with “surgical precision”.
“They were flipping them over, making a very distinctive, almost surgical precision cut down the chest. They would even remove the gallbladder outside the body, which contains toxic bile salts. They knew to remove that bit.”
“In the medium-sized toads, as well as eating the heart and liver, they would strip off the toxic skin from one or both legs and eat the non-toxic thigh muscle.
“All carcasses had an incision in the chest area, measuring [on average] 10.8mm vertically and 12.2mm horizontally,” it said.
“There was no evidence of bites to the head or body of the partially consumed toads. Rather, the rats appeared to hold the toad on its back and then incise the thoracic cavity to consume organs while the toad was still alive.”
