I am not trying to be rude, But I do not think it is right for Kari to get taken away to the shelter, just because a new kitten is in the picture.That is awful and cruel. Your original cats ALWAYS take rank over new ones. (and why would she get another, KNOWING that Kari hates them) Of course she is going to get hissy,you cant just throw them together. You have to keep them seperate and work your way up to introductions (esp. if you KNOW that Kari hates other cats). Put the kitten in a carrier and let Kari sniff for awhile. Then put Kari in and let the kitten sniff her. You can not force it in the beginning. Give them time to adjust. They can get along, if you have patience.

And isnt your aunt the one who just got a kitten and it was killed by a car? If so, then PLEASE PLEASE PLEASE encourage her to keep her cats INDOOR only, because if I remember correctly she lives near a pretty busy road and that is ASKING for her new kitten to be killed. And if that is the case, then it would be better off at the OSPCA. Just my opinion.

THIS IS NOT AIMED TOWARDS YOU- ITS FOR THE CATS OWNER!
