BOULDER, Colo. -- Charges are expected for a man accused of killing a kitten by beating its head against a bookcase after it chewed through his wife's oxygen tubes.

Charles Kenneth Corwin turned himself in on Thursday, on a felony arrest warrant for aggravated cruelty to animals, reported the Daily Camera.

On Friday, Boulder police arrested Corwin's son, Charles Corwin Jr., after police said Charles Jr. was threatening his father with a knife.

His father told deputies his son was angry with him because he had killed one of the family's pets, the Camera reported. He said the cat chewed through his wife's oxygen tank tubing after she had just been released from the hospital.

Two days later, Corwin Jr. came home, after bonding out of jail, and shot himself to death in the bathroom, police said.

When officers arrived at the home the second time, they learned about the alleged feline abuse.

An arrest affidavit said Charles Corwin told police he thought about strangling one of the cats but figured that would take too long.

His son came out of the room and demanded to know which kitten had been killed, and then threatened his father with the knife, police said.

Aggravated cruelty to animals can be punishable up to three years in prison and a $100,000 fine and anger-management classes.
