Are primates the only animals that catch the flu and fever?

All mammals and birds can catch the flu (influenza virus). Humans are not the only species that can get the flu. The reason it is called swine flu is because it is a type of flu virus that originally came from a pig. The pig flu virus mutated with a human flu virus to create H1N1. Other examples of animals that get flu is avian flu (bird flu), dog flu, and horse flu. I have a BS in molecular biology.
