Introducing a new cat

Question
I would like to get a 2nd cat. I've heard differing opinions on whether it's smoother to introduce a kitten to the older cat, or whether the cat should be in the same age group. Do you have an opinion? I plan to follow a gradual introduction protocal as described by my local SPCA. Do you think pherome diffusers would help? Thank you.

Dog Crate I use for ca Elyse,

Personally, I would not get a kitten with an older cat unless you get two kittens.

The most important thing about introductions is to go SLOWLY! Do not try to rush it or force them together or you WILL end up with behavior problems. I am including some excellent links to articles on how to do the introductions properly. They should be helpful as a guide.

Most cats do not like kittens until they have grown up. Older cats usually do not care for kittens because of their energy level, smell, and the fact that they ruin an older cat's routine and peace. A kitten, if it is healthy, will have lots of energy and will like to play a lot. When the only other playmate for the kitten is an older cat he will try to play with her as she would another with another kitten. That causes problems. For the older cat...and for the kitten, who gets confused and can get depressed and can lose heart because the older cat won't play and will growl at her. As the kitten grows and gets more secure and self-confident he may intensify his annoying behavior towards your older cat out of boredom or to expend energy. That may cause the older cat to become stressed or cause behavior problems (like inappropriate elimination) or it can cause the older cat to be aggressive towards the younger cat out of frustration.

When you get a kitten for an older cat you should get 2 kittens, or the new friend for a resident cat should be one close in age and temperament (gender doesn't matter). When you have 2 kittens they play together with rough-house kitty play, chase each other, and play normal kitty games, and then snuggle together for comfort and companionship. They tend to leave the older cat alone more. That relieves the older cat if she is not interested in playing, but leaves the option open if she does.

Growling, slaps, and hisses are nothing to worry about. They are just "kitty communication". That is the way the older cat tells the younger cat to keep her distance, what the rules of "his house" are, etc. When to be concerned is if there are ears pinned back, blood being shed, or major fur flying.

Once the cats can be together without being aggressive, or freaking out, feed the cats yummy cat treats periodically (like tuna, sardines (in oil) or pieces of raw steak, etc.) TOGETHER. That is so the cats will associate each other with something pleasant. Also getting a pet laser light (at Petsmart, Petco, etc.) is great for interaction between the cats. They can chase the 'little red bug' on the floor, ceilings, and walls, and they tend to forget about the other cats as they focus on the 'bug' which helps them get used to each other.

Instead of putting a new cat or kitten in a separate room, I use a large dog crate (48x32x30) that I got at Petco. The cats can smell, growl, hiss, etc. at each other, and get used to each other by being together, but safely. You can let the new one out a little at the time. Plus the new one gets used to the noises and movements of the people in the home and is not secluded alone in a room by itself. I am attaching a picture of the cage that I am using for fostering some kittens. It's also great for catsitting! As you can see there is plenty of room for everything.

I hope this helps.
