Lol! Your piggie sounds like my cat. Charlie's favorite toy is a noisy, small, crumpled up piece of paper. He's even a bit slow to react to catnip sometimes! Go figure. XD

Anyways, I would feel most comfortable going w/ what Piper said. Thats sorta like how we convert piggies, dogs, cats, etc. to a new food, so perhaps your piggies would prefer a gradual adjustment. Don't go back to Kaytee unless its all you have in an emergency. : )
