I purchased a G.p.p's on sunday, nov. 14th. My new leo has been eating everyday, he gets soaked everyday and he is kept both humid and warm. He its pooping regularly and seems healthy, but he has yet to gain any weight. He weighed 49 grams the day I picked him up and still weights 49gr today. No runny nose, and his eyes look alert, he moves around also. Should I be worried? Maybe worms or parasites?
