Upper respiratory disease in cats
Cat flu is the common name for a feline upper respiratory disease, which can be caused by one or more possible pathogens:
- Feline herpes virus, causing feline viral rhinotracheitis (cat common cold; this is the disease most associated with the "cat flu" misnomer),
- Feline calicivirus,
- Bordetella bronchiseptica (cat kennel cough), or
- Chlamydia felis (chlamydia).
