How do you pet a psychopath's cat?
You get it out of the microwave.
The joke plays on the stereotype of psychopaths being cruel and lacking empathy. Instead of petting a cat in the usual way, the punchline reveals a disturbing act of putting the cat in a microwave, implying violence and disregard for life. It's dark humor because it finds humor in a morbid scenario.
