My 1 year and 4 month old leopard gecko usually eats 20-30 crickets in weeks I feed him crickets only. Is that a good number of crickets? He eats medium. Should I increase or decrease the number of crickets? Also on the poop corner, I have a piece of paper so I can easily remove it and it doesn't get on the reptile carpet. Is it okay to use facial tissues as the paper on the poop spot?
