What are the symptoms of feline upper respiratory tract infection (URI)?

The main symptoms of feline URI include: sneezing, coughing, runny nose, lethargy, reduced appetite, significant increase in body temperature, increased eye discharge, and upper and lower eyelid adhesion. However, these symptoms are similar to those of a common cold, making it difficult to detect in the early stages. A PCR test at a veterinary hospital is necessary for a definitive diagnosis.

What are the early symptoms of feline URI?

In the early stages of feline URI, cats may have some transparent secretions around their eyes and nose, along with symptoms such as sneezing, runny nose, and reduced appetite. As these symptoms are similar to those of a common cold, owners may easily overlook them or treat them as a cold, leading to exacerbated symptoms and delaying proper treatment.

What are the late symptoms of feline URI?

As feline URI progresses to the late stages, the secretions around the cat's eyes and nose will gradually increase, becoming more sticky or even purulent. For example, purulent rhinorrhea can cause breathing difficulties for the cat, leading to low-pitched, rumbling sounds. Additionally, it can cause obstructions in the cat's gastrointestinal tract, and in severe cases, even threaten the cat's life.
