Are you giving alfalfa hay? Alfalfa will turn chinchilla urine red.
I didn't know that. Goes to prove, you can learn something new every day!
How long should they have the cranberry juice? I'm not sure if there pee did change color bc i didn't know what color it was before. I just fig it had changed color. ...
I usually keep them on in for a couple of weeks ... it tends to help flush out the system.
If I am giving it because they are dehydrated, (backbone beginning to show and weight loss) I keep it up until they have gotten all or most of their fluid back into their systems and are looking healthy again. WARNING: They do tend to like the taste, so you may have to wean them off of it by decreasing the amount of cranberry juice and increasing the amount of water over a period of a week or two, until you get them back to plain water again.
