We’ve compared five cat breeds known for their low aggression and gentle temperaments, and summarized breed-specific health considerations and key points to check before adoption.



Health Precautions for Brachycephalic Breeds
Brachycephalic breeds, such as Persians and Exotic Shorthairs, have flat faces that can lead to nasal and nostril deformities, making them prone to breathing difficulties and blocked tear ducts. Symptoms of brachycephalic syndrome can worsen depending on the degree of skull deformation, so regular veterinary monitoring is especially important. Before adopting, be sure to review the health history and genetic test results of the cat’s parents. For breeds with Persian lineage, it is essential to confirm whether they have been tested for polycystic kidney disease.
