Feline Viral Rhinotracheitis (FVR) / Feline Calicivirus (FCV)
FVR and FCV are feline respiratory diseases. They both may result in nasal and ocular discharge, conjunctivitis, ulcers of the oral cavity, anorexia, depression and inflammation of the upper respiratory tract.
FeLv produces immunosuppression which can lead to other diseases or infections. Cats that survive these initial disease may develop some form of cancer, hence the name feline leukemia. The disease is transmitted by direct contact with other infected cats, food dishes or litter boxes.
