Our turtle is shedding. Is that normal? Are we doing something wrong? Is he growing? He doesn't seem unhappy, or ill he eats well (didn't like the gourmet crickets we got for him), he's pretty active. On a different note, is there a place to get reptile lights that last longer than a week? For that price, I'd like them to last YEARS, but the six-day light really hacked me off.
