The Cat Group opposes breeding of Bully and Dwelf cats: full analysis

The Cat Group has formally come out against the breeding and promotion of Bully and Dwelf cats, saying the animals are being bred for physical deformities that undermine welfare and quality of life. In its position statement, highlighted by Veterinary Practice on August 23, 2024, the coalition said these cats can suffer from hairlessness, distorted limbs, and abnormal joints that are painful, restrict movement, and interfere with normal behaviors.

The intervention fits into a wider shift in feline welfare policy. International Cat Care’s veterinary arm has been working with the Federation of European Companion Animal Veterinary Associations, the Federation of Veterinarians of Europe, and the Union of European Veterinary Practitioners on a campaign discouraging the use of brachycephalic and other extreme-conformation cats in advertising. Their joint letter argues that visible traits such as folded ears or extreme facial structure often signal deeper health problems, and says the profession has an ethical duty to discourage breeding that causes suffering.

Recent government-backed analysis in Great Britain has reinforced that direction. The UK Animal Welfare Committee’s opinion on current and emergent feline breeding practices, published December 19, 2024, reviewed welfare risks tied to genetic selection and extreme conformation. Among its findings, it said Scottish Fold cats almost inevitably experience pain linked to osteochondrodysplasia, and that Munchkin-type dwarfism can impair mobility, grooming, and other natural behaviors, with some cats developing painful abnormal joints, osteoarthritis, and intervertebral disc disease. The report also noted that related short-legged breeds produced from Munchkin lines are likely to face similar welfare problems. That matters here because Dwelf cats are generally described as composite novelty cats derived from hairless, short-legged, and curled-ear lines, making the welfare concerns cumulative rather than isolated. That last point is an inference based on the report’s discussion of the component traits, rather than a direct assessment of Dwelf cats as a named breed. (gov.uk)

Breed registry policy has been moving in the same direction for years. The Governing Council of the Cat Fancy says it opposes breeding any cats whose physical structure could affect welfare and has, since the early 1990s, discouraged recognition of breeds based on abnormal structure or development. GCCF also states that it has no intention of registering additional hair-deficient breeds, noting that genes causing hairlessness can have harmful effects on other structures such as teeth and mammary glands.

There is also a regulatory backdrop. Scottish government guidance for cat breeders says no cat should be bred if its genotype or conformation could reasonably be expected to harm its own welfare or that of its offspring, and specifically notes that breeding Munchkin and Scottish Fold cats would likely breach that condition. While Bully and Dwelf cats are not singled out in that guidance, the policy logic is relevant because these novelty types are associated with the same kinds of conformational extremes that regulators and welfare groups are already scrutinizing.

Expert and advocacy commentary outside the formal statement has sharpened the message. Reporting on the Bully cat trend cited veterinary and animal welfare concerns that combining hairlessness with dwarfism may intensify existing health problems, and linked the trend to a broader market for novelty pets bred around appearance rather than function or welfare. Separately, Royal Veterinary College VetCompass materials on cat longevity have shown that Sphynx cats have among the lowest life expectancy figures reported in the dataset, adding context to concerns about propagating additional extreme traits on top of a hairless phenotype.

Why it matters: For veterinary professionals, this story is less about one statement than about the consolidation of a veterinary consensus. Welfare groups, registry bodies, and government advisers are increasingly aligned that breeding cats for deforming traits, especially when multiple extreme traits are combined, creates predictable clinical burdens. That can mean more orthopedic pain, mobility impairment, chronic dermatologic care, grooming challenges, and difficult conversations with pet parents who may not understand the health tradeoffs behind a social-media-friendly look. The Cat Group’s statement gives clinicians another credible reference point for preventive counseling, breeder due diligence discussions, and client education around ethical sourcing.

What to watch: The next phase is likely to center on whether opposition from veterinary groups translates into stronger breeder oversight, advertising restrictions, registry action, or updated welfare guidance for emergent feline types, especially as UK and European organizations continue coordinating on extreme-conformation messaging.
