I am going to say "yes" on that one. Kinda like the yawning syndrom in humans!! LOL +5

I never thought about it, but it does seem to.

Sorry, but I just can't clean any of my possible responses to this one up enough to post on AB!!! Thanks for the Q, though. I'm still rolling!!!

I'd say so!! mine copy eachother all the time!! :-) hence the saying "copy cat"!!

Grooming is another behavior which is normal for cats. Cats may spend up to 30% of their waking hours keeping their hairdo coiffed. Grooming another cat in the house is also normal behavior—we call this allogrooming. If your cat likes you, he may try to give you a little washing up with his barbed tongue too! When a cat grooms, backward pointing spikes on her tongue function much like the teeth on a comb. These spikes rake debris from the cat's coat and pull out loose fur, which prevents mats that can cause abscesses and skin infections. Aside from its primary hygienic function, grooming is also a method of thermoregulation in the cat. Cats do not sweat over much of their body surface: Their sweat glands are clustered in a few specific areas, like the paws. Evaporation of saliva deposited on the fur by licking keeps cats cool in hot weather. This is one reason why cats' water consumption increases in hot weather. In cold weather, a well-maintained coat serves as a good insulator. Licking stimulates glands in the epidermis to release secretions that make the coat more water resistant. Cats licking of their wounds are an appropriate behavior, since cat saliva has an antibacterial action that helps reduce likelihood of infection. Licking can be performed as a displacement behavior. In this instance, it serves as a substitute activity and helps to reduce tension that arises from conflict. Cats are known for their fastidious cleanliness. They groom themselves by licking their fur, employing their hooked papillae and saliva. As mentioned, their saliva is a powerful cleaning agent and deodorant. Many cats also enjoy grooming humans or other cats. Sometimes the act of grooming another cat is initiated as an assertion of superior position in the pecking order of a group (dominance grooming). It is interesting to note that behavior specialists believe that grooming behavior, which includes petting, is more commonly done "down" the social hierarchy. What this means is that the more dominant cats tend to do the most social grooming.

for my cat its usually a full tum that motivates her to clean behind her ears! :D

It could but not always. It isn't like a yawn. If a cat is grooming itself it is calm and relaxed. That must mean that the surroundings are calm and relaxed in which case if there were another cat in the room it would be feeling calm and relaxed as well. However there is the odd time that one of my cats is full of vim and vigor and it doesn't matter who is grooming, it will pounce and try to play.
