Norwegian Forest — FDA Adverse Event Profile

Norwegian Forest Pet Health Insights

Across the FDA Center for Veterinary Medicine adverse event database, Norwegian Forest accounts for 184 submitted reports and currently ranks #188 by report volume within the cat population. Of those reports, 11 involved a death outcome — a 600.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 8.9 years, with an average recorded body weight of 5.8 kg (12.8 lbs). These figures reflect the voluntary reporting pool only and should be read alongside breed popularity, veterinary access, and owner awareness — all of which shape how many events ever reach the FDA.

The most frequently reported clinical signs for Norwegian Forest are Vomiting (32 reports), Lethargy (see also Central nervous system depression in 'Neurological') (27 reports), Anorexia (17 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Frunevetmab appears in 20 reports and is the single most-referenced drug, followed by Selamectin (18) and Spinosad (18). Counts like these surface which therapeutic classes dominate the reporting stream — useful context when comparing reactions across breeds of the same cat species.

Outcome coding on the 174 reports with a recorded status is dominated by Recovered/Normal (33.3% of coded outcomes). Annual submission volume ranges from 2,010 to 2,025 reports across the 16 years on file, indicating the reporting trend is shaped as much by awareness cycles as by underlying clinical events. Because FDA adverse event reports describe correlation rather than causation, these numbers are most useful as a signal of where to ask further questions with a veterinarian — not as a standalone risk score for any individual cat.
