Sneezing and eye tearing in cats is often the result of a viral upper respiratory infection. Symptoms may include sneezing, eye or nasal discharge, nasal congestion, eye squinting, lethargy, and inappetence. Common causative agents include herpesvirus and calicivirus. The fact that he is eating and drinking normally is a good sign. However, because he is an older kitty, it will definitely require close monitoring to ensure his signs are not worsening. An exam with your veterinarian is recommended to make sure that his vital signs are normal, including a normal temperature. If he'll let you check his temperature at home, you can. I suggest lubricating a thermometer and checking his temperature rectally. Normal temperatures for can range between 100.5 to 102.5. If his temperature is 103 or higher you should consider bringing him in to your vet. Additionally, if you see yellow/green discharge from the eyes or nose, increased frequency of sneezing, lethargy, loss of appetite, or open-mouth breathing I suggest bringing him to your vet right away. Viral infections, just like in people, can weaken the immune system allowing bacterial infections to occur, which requires veterinary prescribed antibiotics. If there are any other cats in the house, I recommend temporarily isolating them from your sneezy cat until his signs resolve. Minimizing environmental stress is also recommended for his recovery. If you have any other concerns or are interested in additional information I'm happy to follow-up with an online consultation.
