Great appetite, I can hear it crunching kibble, no drooling, just gum redness, swelling, and bad breath.
Expert Answer
Based on your description, the cat has red, swollen gums and bad breath but normal appetite; this may be gingivitis from tartar, bacterial infection, or viral infection. If a cat has tartar, it usually causes red gums and bad breath. In addition, if the cat’s gums are scraped by a foreign object and get a bacterial infection, red gums and bad breath may also appear. Furthermore, infection with calicivirus, herpesvirus, or leukemia may show these symptoms. Check whether the cat has tartar; if so, take it to a vet for dental cleaning. If there is no tartar and no gum wound, it is probably viral, and a prompt vet visit is advised.
