To introduce the new snowshoe to your dilute...

Keep your new cat alone for about three to four days. Slowly offer her food or a treat everytime you go and visit her...just small portions. She will relate you with something great. Once she is okay with you, place her in a cat carrier and put her in a larger room (where your other cat is usually at). Let them hiss it out....but only do this for about 15 minutes. Then the next day, place you dilute in the carrier and place it in the room where the new kitty is. Do the same as the previous day. Do this a couple of times each. Then just open the door to the room and let nature work. It will take up to a good four months for cats to adjust to each other. Some do it sooner, some take longer. It will be okay though. Good luck!
