Hello. I would say you are exactly right, that Simba has an upper respiratory infection, essentially a cold. If he is eating & drinking fairly normally, then you probably do not need to rush him to the vet as colds often just need to run their course. As to why your female seems fine? Well, there is a good possibility she could start sneezing in the next week or so. Again, if the symptoms are mild, you may not need to do anything, but if either kitty quits eating or the ocular nasal discharge becomes thick or green, or you detect any problems breathing, then you will need to have them treated by your veterinarian. If your kitties have not had a full series of kitten vaccinations, which include the most commonly encountered upper respiratory infections a cat can contract, please make sure you complete the series as soon as everyone is feeling better.

    The most common reason that we will see sneezing and watery eyes in young cats is an upper respiratory infection. I am attaching a handout with more information about that below. https://www.vin.com/apputil/project/defaultadv1.aspx?pId=19239&SAId=1&id=4951489 It is very common that young cats will be exposed to upper respiratory viruses at shelters or breeders. It will likely pass on its own, but if Simba is not eating normally, does not seem to feel well, or develops green or yellow nasal or eye discharge, I would recommend consulting your veterinarian. Good luck! I hope that was helpful and answered your question. Thanks for using PetCoach.

    It could be allergies, or it could be Tigger has a respiratory infection. I would take him into the vet in the morning. The vet can diagnose what is causing his symptoms, and can treat him. Best of luck.

    The most common reason for cats to sneeze is a mild upper respiratory infection like feline Herpes virus. This particular virus is like the human cold sore and llves in the cat its entire life, presenting when the cat is under some kind of stress. Most cats have mild bouts of sneezing and ocular and nasal discharge. Over the counter Lyceine is the only treatment, and you can get this in a flavored form from your vet.

    Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, this is most likely an upper respiratory infection which are usually easily managed with antibiotics and topical therapy. Otherwise, this may be due to allergies. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. Good luck and have a great day!
