Cat hugs another cat

You have probably heard your cat emit a fast and intense teeth chattering- especially when they spot a bird while gazing out of a window. Behaviorists speculate that this is because your cat is frustrated that they cannot get outside to hunt prey. They also may be excited and slightly aggravated.

Others say that this strange jaw movement may be your kitty’s natural instinct that allows their muscles to prepare for the act of killing prey. Either way, this behavior is completely normal for your feline.
