Once started it is hard to get it out, little snakes it isn't so much an issue but large snakes ... I have 13 snakes to feed watching each one would take three and a half hours, forgetting the time to prep warm and zombie dance and that is only 15 min an animal I have a few that are very slow and one who often takes at least 2 pick it up and re warm and new zombie dances before she figures it out.
I use a coco coir product it is easy to spot clean and faster than a full clean paper takes every poop pee. In the end it doesn't really matter there is no this is best and everyone uses it there is no clear option it is what works for you.
I change it all every month or so... depends on the animal some are messy and it might be sooner and some clean and it may go longer. This time of year with the hunger strikes it is farther apart.
