I haven't seen him defecate, I am wondering if he is constipated. He seems to be showing this behaviour less than before, though, which relieves me. They do not get any extra vitamins besides a very varied diet and calcium powder. Should I get a vitamin supplement? They do not have an UV but get natural (indirect) sunlight. The toad very rarely calls (he release calls if I handle him, though), and the frog has been silent ever since I got him (although he release calls if I grab him gently by the sides).
