The boys are shown on video abusing the kitten in several ways before one of them raises the animal above his head and slams it to the ground.
The video then shows the boys tossing the “limp and lifeless kitten” over a fence and into a pool.
The cruelty took place in mid-October but the arrests weren’t made until Sunday.
Chandler police Sergeant Joe Favazzo confirmed the boys were in custody calling their crime a "horrible, horrible case of animal cruelty.” The six boys range from seven to 12 years old but only four were arrested.
The seven year old is too young to be charged and one boy is said to have watched but not taken part.
The video shows the cat trying to escape on several occasions only to be re-captured and subjected to more torture.
Cops believe the kitten was less than two months old.
Names of the boys were not released due to their ages.
