Hello everyone i was cleaning my guinea pig cage today and noticed that there was some reddish/brown spots on the fleece. I cleaned their cage yesterday so i know it was from today. I fed them kale and arugula yesterday night and this morning only kale. I thought maybe it is just a weird stain but there are two stains. I'm really worried and i'm not sure if this is normal or not. I have attached photos of these two stains. Thank you.
