My hamster makes squeaking ‘pu pu’ sounds, a few times a day, for about ten days; enrofloxacin 4 days has not helped much.

Hamster squeaking usually comes from respiratory infection, including cold, allergy, or asthma, or from dusty bedding. Check for other signs and bedding dust.

If sneezing and more nasal discharge appear, suspect a cold and use small-pet anti-inflammatory medicine under veterinary guidance.
