Coconut fiber is some sticky stuff. Going to switch to Spaghnum moss. I heard both can cause impactation. Coconut fiber sticks to my frog and pretty much everything else. Plus feces doesn't stand out like it does with moss, which I prefer for cleaning purposes. I just want to know what everyone else has to say. Sorry I have tried to upload pictures but im on a chromebook and its a mission to resize pics. Thanks
