My cats have cold symptoms: sneezing, eye discharge. Is a vet needed?

Hey there. Thanks for using Petco Pet Education Center, formerly Petcoach. I am sorry to hear about your predicament with both your kitties. Based on the symptoms, I would agree that this sounds most likely like an upper respiratory condition. However, without a physical examination with a stethoscope I could not confidently say whether or not the lower portions of the respiratory tract are also affected (pneumonia or heart problem). For this reason, a veterinary examination at the very least is my recommendation to try and rule out something more serious. Upper respiratory infections do not typically resolve on their own and tend to get worse slowly. Most of them, particularly those affecting the eyes, are thought to have both viral and bacterial components. The Wapiti Chest formula is an all natural product meant to support existing respiratory health and does not make any claim as to its ability to rid the body of existing infection. This product would be a waste of your money at this time and I would not recommend it. Your kitties most likely need antibiotic / antivirals to combat the infection. Doctor may also recommend medication for the eyes / nostrils depending on the physical exam findings. While I understand the financial constraints, it might be best to deal with things now before they become worse and more expensive to tackle. Hope this makes sense.
