I have a 7 or 8 month old lab rat named Lucky. Today I gave him his first bath, used Dawn and a Whitening Shampoo on him. Bathed him in the sink, in warm water. anyway, when i was drying him off, i noticed some blood on the wash cloth. So i look him over, and his nose was pinker then usual. so i dabbed his nose with my finger, and there was speck of blood on my finger. Do rats get nose bleeds? Is that okay?
