Can cats catch a cold? A feline upper respiratory infection (URI) is similar to a common cold in humans. If you kitty is sneezing, has congestion and nasal or eye discharge they may be suffering from an URI. URIs are usually viral and are highly contagious. Unfortunately, antibiotics are not very effective and supporting your cat's immune system is the best course of action. Ask Ariel's Immune Support Kit is a trio of natural supplements designed to support the immune system and to fight viruses and infections. Holistic treatments for a feline URI can help stop URI symptoms and improve your cat's well being.
