I haven't seen any new poop from my gecko in about a week. It still seems active when I try to catch it and doesn't seem to have any trouble walking. Its still eating so I'm not sure why I haven't seen any new poop.

What are the signs of impaction that I should keep a lookout for? Could it be possible that it has a parasite or some other type of sickness?

Again, it doesn't have any trouble walking around.

Thanks in advance
