Pedigree cat breeding has lengthy had its controversies however a brand new pattern for cats bred to appear like American bully XL canines might be one of the vital worrying fads but.
So-called ‘bully cats’ originated within the US and are a results of mutant breeding.
Not like pedigree breeding, which focuses on maintaining animals purebred, mutant breeding entails deliberately combining genetic mutations to create cats with a selected look. On this case, they combine the gene that causes hairlessness in sphynx cats with the gene chargeable for the brief legs of munchkin cats, making bully cats a munchkin-sphynx cross.
These cats share an in depth resemblance to bully canines, a bunch of breeds characterised by a stable construct, huge physique and brief coat. American XL bully canines have been banned within the UK in 2023.
Lately, bully cats have made their solution to the UK, the place social media accounts selling this new mutant breed have emerged.

In keeping with Marjan van Hagen and Jeffrey de Gier, animal welfare and copy specialists at Utrecht College in The Netherlands, these mutations can have severe well being penalties for the cats and restrict their freedom of motion. Kittens have already got a restricted skill to manage their physique temperature and that is made much more troublesome by hairlessness and makes them extra inclined to respiratory infections.
A scarcity of fur may result in sunburn and pores and skin most cancers in hairless cats. Just like the sphynx, bully cats additionally lack whiskers, which cats rely on for communication, navigating their atmosphere and gauging spatial dimensions.
Brief-legged cats additionally face issues. Brief legs restrict their skill to leap, can put cats at a drawback in fights and might result in painful well being situations. Though breeders declare that bully cats are wholesome and long-lived, it is nonetheless too early to find out their long-term well being and welfare.
Some breeders additionally say they’re screening the cats they breed from for situations resembling coronary heart illness. This may also help forestall well being issues, however it will possibly’t overcome all the well being and welfare points with mutant breeding.
A Could 2024 research by veterinary epidemiologist Kendy Tzu-Yun Teng and colleagues assessed annual life expectancy in UK cats and located that the typical cat lives almost 12 years, however sphynx cats have the shortest lifespan — simply 6.7 years. Bully cats, being each hairless and short-legged, could face twice the variety of challenges encountered by sphynx and munchkin breeds.
Within the wild, unrelated species that face comparable environmental challenges usually develop related traits, a course of often called “convergent evolution”. Regardless of coming from completely different evolutionary paths, these species evolve to look and behave in related methods.
Take the sugar glider from Australia, for instance. It appears to be like and behaves very like the US flying squirrel, but one is a marsupial and one is a mammal. Each animals confronted the issue of find out how to transfer effectively in a forest cover, and developed the identical answer.
In an analogous means, many domesticated animals share widespread traits, collectively often called “domestication syndrome” together with elevated tameness, juvenile habits, floppy ears and smaller enamel. Traits that helped them modify to life with people.
Nevertheless, the resemblance between bully cats and canines does not come from this gradual, pure course of. As an alternative, it is the results of selective breeding primarily based on aesthetics.
Veterinarian and animal welfare scientist Wenche Farstad summarizes this as breeding for “curiosity or cuteness” of their 2018 paper on moral breeding. Whereas individuals usually discover traits like spherical eyes and brief nostril size to be significantly cute, breeding for hairlessness and shorter legs is best aligned with the idea of breeding for curiosity.
On this case, the resemblance between bully cats and canines is extra about human-driven design, the place look is prioritized. The bully cat appears to have been deliberately bred to resemble the bully canine, maybe resulting from their notion amongst younger males as a type of standing image.
May bully cats survive with out people?
Mutations that hinder survival and copy sometimes grow to be uncommon in nature. Nevertheless, people bypass pure choice by selecting which animals breed, permitting traits that will be disadvantageous within the wild to persist.
Examples of this may be seen throughout plenty of home species. For instance, because of the muscularity of their calves, Belgian Blue cattle require caesarean sections in additional than 90% of births.
One other farm animal, the trendy broiler hen, has been bred to develop a lot quicker than its wild counterparts. If allowed to dwell longer than their traditional slaughter age, many wouldn’t survive. Bully cats would most likely additionally battle to outlive within the wild, with out people to look after them.
Crossbreeding applications may also help enhance genetic variety and cut back dangerous traits in lots of breeds. Nevertheless, for mutant breeds just like the bully cat – the place hairlessness and brief legs are defining traits – this is not a practical answer.
Potential pet homeowners want to concentrate on the dangers related to proudly owning mutant and experimental breeds. Customers maintain buying energy. We will discourage breeders from prioritizing aesthetics over the well being and welfare of the animals by refusing to purchase breeds with excessive traits.
A trend towards moral breeding might guarantee future cats are more healthy, happier and free to get pleasure from pure feline habits like climbing, leaping and lounging within the solar. We must always let cats be cats.
