Abyssinian cat: adverse event reports
FDA breed label "Abyssinian cat" · single-breed animals only
250 adverse event reports received by FDA describe an animal recorded as Abyssinian cat (FDA breed label "Abyssinian cat"). That is 0.2% of all reports about cats. Crossbred animals are not counted here, only reports that give this single breed.
17 reports arrived in the 12 months to March 2026, up 13% from 15 in the 12 months before. A breed's count mostly mirrors how common the breed is; registration and ownership figures by breed are not public data, so no per-animal rate can be given.
By active ingredient, the drugs named most often are selamectin, cefovecin sodium and frunevetmab. Selamectin is named in 15.2% of this breed's reports, about the same share as in reports about all cats (14.8%).
The terms listed most often are anorexia (12.8%), vomiting (12.4%) and application site alopecia (9.2%). Anorexia appears in 12.8% of reports, a larger share than in all cat reports (7.3%). 45.8% of reports stating seriousness were classed as serious, against 35.6% for cats overall.

Ordered by report count. Differences from the species column often come from body size (which drugs a breed is prescribed) and from how common the breed was in the years a drug sold most. FDA states that these data cannot be used to estimate risk or to compare one product with another. Brand and manufacturer names are masked by FDA in these records.

Questions about Abyssinian cat reports
How many FDA adverse event reports involve Abyssinian cats?
250 reports through March 2026, 0.2% of reports about cats; 17 in the latest 12 months.

anorexia (12.8%), vomiting (12.4%), application site alopecia (9.2%), lethargy (8.8%) and ataxia (7.6%).
Is the Abyssinian cat more sensitive to certain drugs?
Report counts cannot answer that. They show what was reported, not what a drug did, and they are not adjusted for how many Abyssinian cat animals exist or were treated. Breed-related drug sensitivities that are established are described on FDA-approved labels; a veterinarian is the person to ask about an individual animal.
Why are crossbreds not included?
FDA records crossbred animals with one or more component breeds. Counting them under each component would double count, so breed pages use single-breed reports only. Crossbreds remain in the species totals.
How do I report a problem?
Call the drug company using the number on the label, or send Form FDA 1932a to FDA. See the guide on how to report.
Where this comes from. Counts are built from the openFDA Animal & Veterinary adverse event bulk files released 28 Sep 2026, which hold reports FDA's Center for Veterinary Medicine received through 31 Mar 2026. openFDA masks brand and manufacturer names in these files, so drugs are counted by the active ingredients each record discloses and no figure is attributed to a brand, application or company. Ingredient names, and the separate reference lists of approved products, follow the FDA Green Book as of 1 Oct 2026. Breed names are FDA's labels rearranged into everyday order ("Abyssinian cat" becomes "Abyssinian cat"). No report text, lot numbers or reporter details are published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
