I put Fractal in his revamped infant cage to take him to the vet's. (my vet is no longer here, need a new vet now) Anyway.. it's been a few weeks in the new big cage and I was concerned because he'd not knocked his old shed off and was looking horrible gray, etc. He's been in his old cage for 7 hours and he looks nearly like a brand new chameleon. No gray and now vibrant in color and pattern. Don't tell me he likes his old fake plants and small cage better? What is this phenomenon?
