Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Sneezing can be a sign of a respiratory infection. A handful of different components can lead to respiratory infections in mice, whether viruses or bacteria. Mycoplasmal infections, for example, often occur in mice. When mice have respiratory infections, they often display cold-like clues, including problems breathing normally and runny noses. If your mouse is breathing in a manner that seems inordinately loud, a respiratory infection could be responsible. Other typical symptoms of respiratory infections in mice are weight loss, reduced desire to eat, exhaustion, barely moving around and messy looking fur. The bedding in Popcorn's enclosure could be the reason for her persistent sneezing as well. Ask your veterinarian for types of bedding that are less dusty and cause less irritation to the nostrils. If the sneezing is the result of any illness, your veterinarian can provide treatment options. Remember, mice, like other pets, require regular vet checkups regardless of the presence of signs of illness. Take your mice to the vet a minimum of once annually. If she sneezes or seems sick, go to the vet immediately, even if she just had her yearly appointment. I hope this is helpful!
