When I adoped him, he's files says that he lived with 3 other cats and a dog.

My 2 younger females are very scared (one run and the other one is on protective mode but still ready to run). The older Male (12 years old) look at him for a moment but he is very old and prefare to run i guess. It looks like they smell big danger around him. :-(

Every day I put the new cat in a small cat cage and integrate him with the others (for couple of hours) so they could get used to him.

thank you
:-)
