Yeah, it's fine. I actually
bathe mine with the full expectation that she'll poop in the
bath about 5 minute in. A lot of people's dragons will poop in the
bath. I think something about being in the water must make them go for some reason.
Mine used to poop at least once a day or more, but as she's gotten older, her pooping frequency has gone down. As long as she doesn't look impacted, I don't really worry about it. If husbandry is good, they'll just go when they need to go (or in the
bath, so you have to refill the water, lol)
