Do tailess cats have a communication problem with cats that do have tails?
Cats do use their tails to send out communication signals to others. I read somewhere once, that a cat with no tail might get into more fights or be perceived as threatening by other cats, because they aren’t able to do the raised “happy” cat tail signal. Perhaps this is why your other cats are not quite sure how to react to him. The web site below explains cat communication and their body language in more detail.
