My ferret has green, runny poop. Is this normal or a vet visit?

My ferret has been having poop problems lately. They seem to be pretty sporadic, she pooped a green grainy poop the other day and then was normal, but tonight she pooped a green liquid. I don't know what to do, I know cancer is common in ferrets but she's not even two years old!

Hello there! I'm sorry to hear that Luna hasn't been feeling well. In general, green poop in ferrets means that food is passing through their gut too quickly, and the fact that she had some runny green poop confirms that this is likely the case. Diarrhea in ferrets can be caused by multiple conditions, including parasites (worms or protozoan parasites), dietary indiscretions (eating things she's not used to or not supposed to), and lymphoma (which is unlikely in a young gal like Luna). I recommend that if the green and/or runny poo continues, you should bring Luna to the vet for an exam. They will probably check her stool for parasites, and they may want an x-ray to rule out any masses in her belly. Other ferret-specific diseases like Aleutian disease, insulinoma, and estrogen toxicity are also a concern, but less likely if she isn't exhibiting other symptoms. Good luck, and I hope Luna gets better soon!
