An accused stalker has been busted after the decapitated heads of two cats were left on a Florida homeowner’s mailbox, according to cops.

The investigation into “heinous violent acts” toward “innocent animals” was launched when an unidentified homeowner in Bonita Springs found the heads in a cardboard box on top of their mailbox, Lee County Sheriff Carmine Marceno said.

It was not clear why the homeowner was targeted — nor to whom the cats belonged.

Robert James Luther III, 37, was found to have been in the area at the time and was arrested fishing nearby — with search warrants leading to “disturbing cell phone videos” where he “made mention [of] and depicts the deceased cats,” the sheriff’s office said.

Neither the motive for the disturbing crime nor whether he was known to the homeowner was immediately clear.

However, the suspect was charged with two counts of aggravated stalking as well as two counts of aggravated animal cruelty.

Luther was arrested and charged with two counts of aggravated animal cruelty and two counts of aggravated stalking.

“Heinous violent acts, especially toward innocent animals, is beyond unacceptable and any offender will face severe consequences to the fullest extent of the law,” Marceno said.

“The combined efforts of multiple units ensured this sick individual got locked behind bars before he could hurt anyone else,” he added.

Luther III “invoked his rights” and refused to speak with police. The Post has reached out to the sheriff’s office for additional information.
