Siamese cats are in unfamiliar environments. When strangers arrive at home, they like to hide under the sofa. At this time, Siamese cats’ instinctive reaction is called stress response. They will hide under the sofa when they are nervous and afraid. Dark corners. Breeders can exercise the courage of Siamese cats on a daily basis, take the cats to meet more strangers, take the cats out more often, and expose them to new environments.
