Looks like your Leo is pooping more than it is eating...watch it's weight to see if it is using its body weight for nutrition instead of eating. If you are asking about the powdery-looking poop, that is just dried poop...ya might wanna clean a little more often.
edit: ...but that does look like a normal "week's worth" for a healthy eater.
Yeah the was only a week I clean her cage every Sunday because I go to school and don't get home until 8 so it's hard. But okay. Well I posted something about the weight on my other post if u can go check it out
