It's so strange. I changed out their temporary bedding for fleece. In less than 10 hours, I go look at the fleece and there are little white marks where I'm guessing they have peed. Is this normal? If it is extra calcium, is that a good thing or a bad thing? I'm sorry to sound like a complete idiot. I've had all sorts of rodents, but never a guinea pig. This is my first experience with them and I just want to make sure they are healthy. They are in quarantine right now because I thought one might have ringworm, but now I'm not sure that it was ringworm. If the dry urine is giving off a white residue-like appearance, it's possible that some could have gotten on the one guinea pig (who I thought might have ringworm).
I know bathing a skinny pig can dry out their skin, and moisturizers can clog pores, but I did bathe them last night with baby shampoo. I didn't put any moisturizer on them, though. They were surprisingly filthy (it really looks like they should be scrubbed, but I was gentle and only used my fingers and then dried them in a super absorbent soft cloth wrapped in a layer of fleece for extra warmth). I don't think they were kept clean in their previous environment. I've got a vet appointment scheduled to meet with our new small animal vet. This will be my first time meeting him, but he's one of the best in this area. I've heard a lot of great things about this doctor working with small animals, and he also works on the wild animals living in captivity at the Virginia Living Museum. Hopefully he can take a look at these guys and assess the condition of their health and whether or not fungus may be present.
