I've found that Mr. Jack is very sanitary. He goes to the floor of his cage to poop 90% of the time... At first, I found it worrying that he was wondering the floor. Then I realized every time he does it, there's a fresh to clean up after.
Littlefoot also wanders to the bottom for a #2 around the same spot, every time.
I'm actually fascinated, it's like they're toilet trained...
I had one quadricornus chameleon that would always poop as soon as I cleaned the cage. I’m sure he was re-marking his territory. I don’t know if it was in the same spot or not…I should have paid more attention.
A bit off topic…I had an iguana that was litter trained…like a cat…and it always used the litter box when out of its cage.
