Hmmm... I'll leave this one to the experts because I don't know. My gut says it might be a bad idea, but I don't have any evidence to support my gut other than having never seen wild frogs eat Cheetos.

To treat my guys I feed special foods (like fresh fruits etc) to their crickets and then the frogs get to enjoy the taste (and nutrition) second hand. Apparently crickets taste like whatever food they eat - although I've never verified this! - so varying the cricket diet might be like a treat for the frogs too.
