the only cat that was brought in from the outside (an adopeted, unwanted pet) is Snow Tiger, approx 2 1/2 months of age. He even fought with all the other cats here, usually over food. I remember bringing him home that first evening, he ate so much food! Probably, the people who had him didn't feed him, or the rest of the litter, much and when he came here and saw all the goodies to eat, he probably went into a self-preservation mode! He also hissed and fussed at two of the females who took him in immediately and began to wash him. However, after a week of being here he settled down and now he gets along with all the other cats -no fussing or hissing. When
I brought him home, I didn't think about quarentining him because he looked and acted healthy then, and even more so now. Of all my kitties he is one of the most persistant and aggressive in play. I consider his age as having something to do with his ability to integrate with the crowd. But an older cat would probably have trouble adopting to this menagerie. From this bit of experience, I would probably have to stay with fostering kittens - cats under 9 months of age, and besides, most folks who would like to adopt a kitten more than likely have at least one other cat around their house. Most all of my furkids get along with each other.
