So Sheldon has been constipated that last few days. He has been having a hard time getting his poo out and when he finally does it is really hard. Yesterday after his soak I put him down on the floor with my daughter so I could do some clean up in his tank. My daughter said he was trying to poop and when he finally did it was hard. I picked it up and squeezed it like I have been doing and there was something hard in this one. I pulled it apart and there was a big and I mean big piece of cypress bark in it. He has been eating the bark! I could not believe he ate such a big piece and that he was able to pass it. Just very glad he did. So pulled out all of the substrate and put in only peat moss. So far I think I like it better. I haven't seen a poo today in his bath or in his tank but he'll get another bath in the morning and hopefully he has passed all of it already.
