Feline calicivirus can occur when your cat comes into contact with the discharge from an infected cat. This can mean airborne droplets from sneezing, eating from a contaminated food bowl, or using the same bedding or litter tray as a cat already with FCV. It can be seen after a new kitten is introduced into a home, and FCV can spread quickly in a cat shelter, hospital, or home with multiple pets, making excellent hygiene and cleanliness vital. FCV is typically characterized by upper respiratory symptoms and occasionally arthritis. Other common symptoms and possible signs of FCV include: Discharge and redness of the eyes, sneezing, runny nose, mouth ulcers, a lack of appetite due to blocked nasal passages inhibiting sense of smell, joint pain, lethargy, and, in some cases, symptoms of a fever. When a felines immune system is compromised the mouth, nasal passages, sinuses and upper airways can be affected, breathing can become hampered, and airways can become increasingly blocked and congested.
