Does anyone here have any ideas about how to introduce one mostly-outdoor block cat to a new block that already has a group of cats living on it? I moved recently and learned that the block kitty on my old block is no longer welcome to live under the front steps of my old building. I'd like to bring her to my new backyard, but there is a group of kitties here already who like to come and hang in our yard. Am I being overly cautious in worrying about introducing a new kitty? Does anyone have any experience doing this? Any insight is much appreciated!
