What causes upper respiratory virus in cats?
Upper respiratory virus (URV) is a “cat cold” caused by one of three different types of viruses (rhinotrachetis, calici and chlamydia) Recovery can take anywhere from seven to 21 days. Most cats experience mild symptoms, including sneezing, drooling, nasal discharge, eye discharge, and decreased appetite and the majority will recover without medication. If you notice thick nasal discharge, lethargy, lack of appetite, dehydration, oral ulcerations or fever contact your vet. Never give a cat medication designed for humans—the result could be fatal.
