The breed standard is that Siamese cats are intelligent, vocal, and very attached to their humans. Of course.. this doesnt always happen.
While there is no cat that is purely hypoallergenic, Siamese cats are considered to be as close as possible. They are suitable for most people who suffer from cat allergies. One reason for this is that Siamese cats shed a lot less than other breeds.
It’s believed that Siamese cats first appeared in Siam’s ancient Asian land (nowadays Thailand), and that’s how the breed got its name. According to The International Cat Association (TICA), manuscripts from Siam’s ancient capital first mentioned the Siamese around 1350.
