These symptoms can be caused by a range of diseases, and are often accompanied by severe dehydration. Without an exam and some testing, I can't make a diagnosis, and it is illegal for us to make specific recommendations on medications. You should call your local vet for further advice.

    Lethargy and loss of appetite are very vague symptoms but can be a sign that something isn't right. it's possible that illness, digestive upset, pain, parasites or other issues could be the cause. if it happens for more than a day, or worsens, it is best to seek veterinary care ASAP for Lucky to find the underlying cause. While cats can get the 'flu" the type humans get is usually not the same type cats get, and it is rare to have them passed from human to cat (however not impossible, as a virus can always mutate). Seeking veterinary care for Lucky if his symptoms continue is the best course of action.

    Poor Fatty! It could be a respiratory infection, but he could have something else causing his anorexia and lethargy such as a systemic illness, infection, inflammation, or injury. It is concerning when a cat isn't eating, as if they don't eat for going on three days, they become prone to a fatty liver. A fatty liver is fatal without treatment, so it's best to avoid that from occurring. I would have Fatty seen by a vet today who can diagnose what is causing his symptoms so he can be treated.
