Cats have a very strong preference when it comes to both texture and taste. They maybe leaving their tongue sticking out due to some lingering taste or foreign body stuck in their mouth. They may also stick their tongue out repeatedly.

There is a scientific explanation for this behavior which is used by many animals as part of social behaviour. It is called the Flehmen response and is used to pick up chemical signals which happens when a cat is curious about something such as a scent.
