My cat's runny eyes & congestion won't clear. Antibiotics failed.

My cat always has runny, weepy eyes and really bad nasal congestion. He sneezes huge brown boogers at least once a day. We've tried antibiotics a couple of times but he never gets better. What should I do?

Poor Link! In cats, respiratory infections are typically caused by a virus, so antibiotics won't work. I have a few things you can try at home. First, you can try starting him on an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight. If he's congested, you can also try using a humidifier or bringing him into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections. I would also recommend taking him into the vet tomorrow. An antibiotic ointment could help with his weepy eyes, but those can only be prescribed by a vet. Best of luck, I hope this helps!
