Most tailless cats are not tailless. They have spinal deformities. The Manx, Japanese Bobtail, and American Bobtail carry three different genetic mutations. Only one is healthy.

Feline Infectious Peritonitis: How a Random Mutation Turns a Common Virus Fatal

Feline infectious peritonitis is not a separate virus, but a mutated version of a common one. Learn how a random genetic error turns a harmless gut bug into a fatal disease, and why modern antivirals have changed the outcome forever.

Cats cannot taste sweetness because a broken gene wiped out their sugar receptors 83 million years ago. This article explains the Tas1r2 pseudogene and why obligate carnivores ignore sugar.

The Manx Mutation: Why Taillessness Is a Spinal Deformity, Not a Trait

The Manx mutation deletes the tail but rewrites the spine. Learn how a single dominant gene causes lethal spinal defects, Manx syndrome, and why breeding for the perfect rump kills more kittens than it saves.

The 1954 Spotted Kitten: How a Siamese Mutation Created the Ocicat, Savannah, and Bengal

Some domestic cats look like miniature wild animals. The genetics behind the Abyssinian, Ocicat, and Savannah breeds explain why their coats mimic leopards and tigers.

The Ragdoll Cat’s Flop: Why It’s a Learned Behavior, Not a Genetic Trait

The Ragdoll's signature limpness isn't a genetic mutation. It's a trained behavioral response to early handling. Here's the real story behind the flop.

The Manx Cat's Tailless Mystery: The Genetic Mutation That Killed Its Own Breed

The Manx cat's taillessness is a lethal genetic mutation. The breed survived only because breeders learned to manage the spinal defects it causes. Here is the biology behind the breed's signature rump.
