Whenever we talk about "hypoallergenic" cats , it's very important to realize that no cat is truly hypoallergenic. The allergy is usually caused by a protein (FEL D1) that is produced in the sebaceous glands of the skin, saliva, and urine. When a cat cleans itself, this protein is transferred to the fur. After the cat's saliva has dried, the allergens become microscopic airborne particles people can breath in. Moreover, we all know how easily cat fur spreads all over the house. That's how people contact the allergen, either epidermally or by inhalation. A hypoallergenic cat is a cat that produces less of this protein, and therefore it is less likely than other cats to produce allergic reactions in some people.

Here are some cat breeds are are thought to be hypoallergenic.

The CORNISH REX and DEVON REX shed very little. Besides, their coat is less thick than that in most other cats. This provides less surface area to trap allergens. The same can be said about JAVANESE cats that lack undercoat. They have less fur which result in fewer allergens.

SPHYNX cats have little to no hair and therefore chances that you contact with the allergen are much lower.

The SIBERIAN, even though it's a longhair breed, is thought to produce far less FEL D1 protein than other cats. This has not been scientifically proved but some people who have an allergy to cats have reported that they could keep Siberians and didn't develop allergy symptoms. Other breeds that seem to produce fewer allergens are the BALINESE, RUSSIAN BLUE, and ORIENTAL SHORTHAIR.

Important factors

  • Males produce more allergens than females;
  • Intact males produce more allergens than neutered males;
  • Dark cats seem to produce more allergens than light-colored ones (no one can tell why);
  • Kittens produce less allergens than adults.
So, a light coloured female cat may be a better choice for people with cat allergies, especially if it's one of the forementioned breeds.

It's important to realize that a "hypoallergenic" cat may not be the panacea you're expecting. Before you adopt a cat, spend some time with it, or with a cat of the same breed to see if you get allergic reactions and how bad they are. If you want to get a cat from a breeder, ask if you can return the kitty if your allergy persists (reputable breeders should not refuse). Consider rescue organizations for the breed, they will always accept returns.
