A 49-year-old man has been charged with two counts of felony animal abuse after authorities discovered two decapitated kittens at his home.

Winnebago County Assistant District Attorney Christian Gossett told local broadcaster WLUK-TV on Tuesday that the kittens were found over the weekend in a garbage bag at Donald Agrell's home after authorities received an anonymous tip.

Agrell, who was on probation for a drug conviction, has admitted to the crimes, according to court records. He said the six-week-old kittens were "just psycho" and would attack him, so he felt he had to kill them.

Agrell faces up to six years in prison if convicted.

He gave his other cats — two kittens and their mother — to the Oshkosh Humane Society, which has since placed them up for adoption.
