Does your cat arch up its back to meet your hand when you pet her? This is a sign that she is enjoying the contact. Back arched and fur standing on end means she is frightened or angry. A scared or surprised cat may puff up its fur and turn its body sideways to the apparent threat in order to appear larger.
Have you ever noticed times when your cat will open her mouth slightly, curl back her lips and squint her eyes while sniffing something? This is called the Flehman response. It is your cat’s way of gathering more information about the object she is sniffing. The cat has an extra olfactory organ which is called the Jacobson’s organ. It is located on the roof of the mouth, behind the front teeth and connects with the nasal cavity. By opening the mouth and inhaling, the odor is intensified allowing the cat to obtain more information about the object in question.
