Therefore if you have a cold or flu you should keep handling of your hamster to a mimum until you are recovered to avoid spreading your cold to the hamster.
Hamsters can also catch a cold if the cage is exposed to draughts or are bathed.
Signs that a hamster has a cold are normally sneezing and runny nose. Some extra paper bedding should be placed in the cage and the hamster should recover within a couple of days. If the hamster does not recover after a couple of days or worsens veterinary advice should be sought as antibiotic treatment may be required. Giving a mixture of lukewarm water, milk and honey will also help with the hamster's recovery. Provided colds are treated early before severe symptoms occur the hamster should make a full recovery within a few days.
