We've had our leopard gecko about 4 months and we feed it primarily meal worms. I decided to offer it crickets for a change about a week ago. I bought several small crickets and it ate 2-3 immediately. Ever since it ate the crickets it stopped eating altogether. I also noticed that all of the crickets I bought were dead the next day. Do crickets carry diseases that can be passed along to the gecko? Its been about 5 days since it ate mealworms. When should I worry? Also, it just sheaded but usually it still eats after sheading. Thanks.
