Thanks for reaching out about Munchkin. Red is often associated with blood or porphyrin pigments. Either could be and indication of an infection. If being kept on bedding that is fragrant or perfumed (i.e. cedar, redwood or pine shavings), these aerosols can cause inflammation and thus bleeding. If this is the case, changing bedding to towels, shredded paper might help. Hamsters also like to chew on the bars. Check for broken incisors as this also can cause bleeding in the nose. Monitor appetite and water consumption, fecal and urine production. If any of these are diminished, or becomes lethargic, a veterinary visit is needed.
