A simple infographic covering the salient points when nursing a cat with flu. As you know there is no cure for cat flu as there is no cure for human flu. The body has to do the work through its immune system and the production of antibodies, but you can help the body fight the disease with good nursing. The symptoms of acute respiratory infections (URIs) are well known. But if in doubt on any of this seek vet advice promptly. That said the infographic is based on the advice of four American vets: James M. Giffin MD, Liisa D. Carlson DVM, Debra M. Eldredge DVM and Delbert Carlson DVM.

Cat flu is very common and can be mild to severe. If left unattended secondary bacterial infections can do real damage to the eyes. I’d make sure that you have the right diagnosis. Symptoms alone might not be enough. You don’t want to miss treating a more serious illness and/or an underlying illness.
Cat flu is extremely contagious and spreads in saliva, snot, sneezes and on items such as food bowls and bedding which is why isolation and taking precautions to prevent the spread of it are important in multi-cat homes, catteries and rescues.
