My cat's URI won't go away after antibiotics. What can I do?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 6 lbs

I have taken in an 8 year old cat that has upper respiratory problems. I took her to the vet and he gave me an antibiotic. That was taken and she seems a little better but she stills has it. She does eat and drink, so that is not the problem. I have been giving her a product called Respiratory Support from Only Natural Pet and also a powder called Immune Support. I have been doing this for about 2 weeks now. Do you have any other advice?

Yes, I do have some more advice on how to treat Domina! First, you can try starting her 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 she's congested, you can also try using a humidifier or bringing her 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. Hope this helps!
