Updated On September 23rd, 2025

My cat has a respiratory infection. I cannot afford a vet at all right now. I see online that you are able order antibiotics for cats without a prescription. Just looking for recommendation on which one and what dose?

I'm very sorry your kitty is sick. Respiratory infections are very common in kitties and almost all are caused by a virus, not a bacterial infection. Therefore, we do not recommend antibiotics if we are dealing with an upper respiratory infection. There are several things you can do at home though. To help with nasal and sinus congestion symptoms, I recommend using the shower to fill your bathroom with as much warm steamed air as possible and then place your kitty in the room for 10-15 minutes at a time. You can do this several times a day, the goal is to help humidify the air and allow your kitty's nasal passages to drain and clear some. You can also purchase over-the-counter treats or a gel formula containing the amino acid supplement L-lysine made for cats. These can sometimes help clear a viral infection. Follow the label instructions to know how much and how often to give to your kitty. If your kitty stops eating or drinking, you will need to have it examined by your veterinarian to avoid complications such as dehydration.

    I can give you some things you can do at home for Dusty and her cold, including an OTC supplement. 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. Please do not give her any human pain medications or cold medications as many of them are toxic to cats and are fatal if given. You can also have Dusty seen by a vet to get safe medications prescribed for her symptoms.

    Poor Harry Potter! You will need to take him into the vet, and I can give you some things to do at home as well. Please know these home remedies should not take the place of a vet visit, as he needs to see one to be sure he does have a cold. The vet can prescribe medication as needed. 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.

I hope this helps!
