Some of you may have read that I wasn't the best caretaker the last few months, but I'm changing everything now. I used to feed my Grisha the dry food from "Healthy Herp" that you have to add water to so it hydrates.
Now I quickly switched from that to real collard greens, turnip greens, and squash. I also have been offering him 5 superworms dusted with calcium everyday to have him gain some weight.
He's acting completely normal. Energetic, bright colors, no lethargy whatsoever, just his poops have been watery for the last 2 or 3 days. They're a good color though, and there are urates. He's well hydrated too. Could this be from the sudden change in diet?
Yes changes in poo can result from changes in the diet.
It seems to happen very often when a dragon is fed superworms for the first time, for whatever reason. I would introduce them slow, like 1 or two a day, and then work your way up from there.
