Well, I gave her a ball made of twigs (the kind sold for guinea pigs in the pet store) last week, and she ate it completely within a couple of days. I knew she was pulling it apart, but thought she was shoving the pieces under her bed. It turns out that she only shoved a few pieces under the bed, and the rest was gone. I've been wondering if that might have made her ill.
She is passing pellets normally, but they are a little pointed on the end, as opposed to the normal rounded pellets.
She is passing, what I feel to be, more urine than normal. I cleaned her cage a couple of days ago, but it seems to be quite wet for being so recently cleaned. But I also changed out her beds, so it might be that she's only peeing in the one area of her cage (the bed area is dry), so it looks like more urine than normal. I'm not quite sure.
She doesn't get any supplements, but I just started giving her some parsley after I was told that it was good for vitamin C. I started giving her this after she stopped eating, though, so that doesn't seem to be the cause of it. Other than that, she doesn't regularly get fresh veggies. She does occasionally, when I have something on hand, but not daily. The more I'm learning about guinea pig needs now that she's sick, I'll start giving her fresh veggies regularly if she pulls through this!
I ran out of hay for a while, so she hasn't had any recently. I finally bought her some more today, but she's been living without it for a while.
She has the recycled paper type bedding. She seems to be allergic to pine chips, and sneezed frequently when I used that for bedding.
