Intraoral administration of canine interferon alpha (CaIFN-α) has been shown to reduce gingivitis in dogs, but has not been confirmed in cats. Therefore, in this study, a CaIFN-α preparation was used for feline gingivitis, and the degree and duration of its effects were examined. Cats were divided into two groups: one was administered CaIFN-α, and the other was not. They were observed up to 12 months. It was suggested that CaIFN-α have a reducing effect on gingivitis and halitosis for a certain period although may not on plaque or calculus. In addition, the duration of the CaIFN-α gingivitis-reducing effect was suggested to be about three months. The CaIFN-α preparation is considered to be a useful treatment for oral hygiene control.
