But the turth is that the Savannah breed is no different than any other breed when it comes to inroducing them to another feline (of an breed). We have 200 cats, here, as you know, and they all live together harmoniously in small colonies. BUT, if one day, I took one of the moggies and put it in with a cat or cats it did not know, it would react exactly the same as a Savannah or any other breed of cat. There would be hissing, growling, spitting, biting, and clawing. That has nothing to do with the breed and everything to do with the individual personalities of the cats involved.
