Will a cat’s cold with a runny nose heal on its own?

A cat’s cold is unlikely to heal on its own; usually only a very mild cold in a cat with strong immunity might. Most of the time, without timely treatment the symptoms worsen and can even threaten the cat’s life. For the cat’s health, it is best to treat a cold promptly. Generally, a common cat cold recovers fairly quickly: give pet-specific cold medicine and keep the cat warm, and it will soon recover. But if the cold is caused by a viral infection, the owner should take the cat to a veterinary clinic to be treated by a professional.
