Help with my leopard gecko?

if the gecko is 2 or 3 months old they look pretty skinny. thats normal. just make sure the tail is fat. if the tail is fat that means the gecko is healthy. the closer they get to they're full adult size they'll get pretty big. just keep feeding the geckos the gutloaded crickets and they'll b fine. sum done seem to like the worms. they hav preferences just like we do. hope this helps and good luck :)
