Database median
1270.0% of 110 reports involved a death outcome. Read alongside breed popularity, veterinary access, and owner awareness — these shape how many events ever reach the FDA. The 12% comparison line is the rough cross-breed median in the FDA CVM database; values above suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Tonkinese Pet Health Insights
Across the FDA Center for Veterinary Medicine adverse event database, Tonkinese accounts for 110 submitted reports and currently ranks #224 by report volume within the cat population. Of those reports, 14 involved a death outcome — a 1270.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 9.6 years, with an average recorded body weight of 4.2 kg (9.3 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 Tonkinese are Vomiting (17 reports), Lack of efficacy - NOS (17 reports), Anorexia (16 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Selamectin appears in 15 reports and is the single most-referenced drug, followed by Spinosad (11) and Frunevetmab (11). 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 96 reports with a recorded status is dominated by Ongoing (35.4% 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.
Understanding Tonkinese Adverse Event Data
Tonkinese has 110 adverse event reports on file. Lower report volumes may reflect a less common breed, lower reporting rates, or genuinely fewer adverse events.
The 1270.0% death rate is above average, though this statistic should be interpreted cautiously. Death reports may be overrepresented because serious outcomes are more likely to be reported than mild reactions.
The most frequently referenced drug in adverse reports is Selamectin, appearing in 15 reports. This may indicate widespread use of the medication rather than a specific safety concern for Tonkinese.
