Cat colds?

Ashley

Can cats get colds? My younger cat Roxie was sneezing a lot, itching her ears and nose a lot as well a few weeks ago. I thought she was just experiencing an allergy to the new type of litter we were using (which we got rid of) but now my older cat Morgan is experiencing the same symptoms. Roxie no longer has the symptoms but Morgan still does. Should I just let whatever this is pass? Or should I take Morgan to the vet?
