Shorthair cats

Shorthair breeds have a short, close-lying coat rather than a defining personality — the group runs from the chatty, people-focused Siamese to the calm, independent British Shorthair, so "shorthair" describes the coat, not the temperament.

Not much. A weekly brush is usually plenty to remove loose hair and keep the coat glossy; shorthairs manage most of their own grooming and rarely mat, unlike a longhaired breed.

No — no cat breed truly is. The main allergen, Fel d 1, is a protein in a cat's saliva and skin rather than the fur itself, so coat length has little bearing on how allergenic a particular cat is.

The individual hairs are shorter, so shed fur is less visible and far less likely to mat into tangles around the house, but shorthairs still shed — some, like the Siamese, noticeably during seasonal changes. It's a difference in mess, not in shedding volume.

Generally yes, on the grooming side — low-maintenance coats make them an easy fit for someone new to cat care. Temperament varies enormously by breed, though, so match the individual breed's energy and vocal tendencies to your household, not just the coat length.

Considerable — the group has some of the widest personality range in cats. The Siamese is famously vocal and demanding of attention; the British Shorthair is famously placid and happy alone for stretches; the Bengal keeps a genuinely wild-cat energy. Pick the breed for its temperament, not its coat.
