I adopted a cat a few months ago. He's very sweet but has had limited exposure to other animals, aside from his time in the shelter. He's generally very curious when he smells another animal and has never shown signs of aggression.
I've been considering adopting a female cat as a companion for him. How should I go about introducing them? The cat I am considering would be a rescue from a high kill shelter. They're the same age but she has displayed a "lack of social skills", as in she shys way from being pet by humans.
I figure it's not the best idea to just put them in a room together. However, my current cat was said to be timid in the same way, but totally opened up when I brought him home. Any advice would be greatly appreciated.
Well first of course she has to get used to the new environment, that could take a while depending on the cat. For getting her used to the environment, when I had gotten a new cat, I grabbed a very, very slightly damp cloth and rubbed it over the cats fur and body to get as much of the scent of the cat as I could on the cloth, then I wiped the cloth over a few small points in the home that I knew were going to be in that particular cats vicinity if you're planning on keeping them in a specific area, you don't want to take over the entire place with the other cats scent though, it could overwhelm and give anxiety to your other cat, your other cat needs to get used to the scent as well, but this will help make the new cat feel a bit more comfortable.
You want to get both cats used to and familiar with the smell of the other cat in the same way. Use the damp cloth method, have two for each cat's scent and just introduce the scent to each cat, don't force them to have to be in constant vicinity of it, just place the cloth in front of each cat for them to smell for a few minutes, let them examine it for a while and then walk away. Then in another hour do that again and keep doing it every other hour for a while and for a couple of days. This also helps the cats associate that there is nothing harmful or dangerous about the scent as the cloth obviously isn't hurting them.
I would personally after doing that for a few days, allow them to kind of familiarize with each other, always, always, ALWAYS supervise them when they are in the same room with one another or are near by each other. Give them room to breathe, don't trap them and force them to interact if they are not comfortable with it, they will gain confidence and will test what the boundaries of the newfound relationship are in time.
Keep it slow but steady and progressive and always supervise them. I would keep them separated at night in different rooms when you're sleeping because you never know what could happen or transpire overnight without your awareness.
Eventually as they grow more used to each other and figure out the hierarchy, they'll find a comfort zone and this could be the potential time where they might start forming a bond of sorts. Be wary, but let them explore a bit and know not to stress them out too much. Make it gradual.
