Like many teenagers, Two and a Half Men star Angus T. Jones has a handful of prized possessions in his bedroom. The first is a mini recording studio where the 17-year-old actor and his buddies create new music, the second is his Canon camera and the third likely sheds hair on both: It’s his 4-month-old kitten, Mascot.

“[He’s] super-playful but also very sweet,” Jones tells PEOPLE. “He sleeps in my room and he will come to his name. He’s already litter trained. I can leave my door open and he won’t run away.”
