It is hard because adopting is important but you can't really know what was in a cat's past. One of our cats is very grumpy at the other. This could be caused by something in her past that we aren't aware of. Our other cat also has very poor manners for a cat (he stares at everything) that might have developed by being raised with other animals.

What I wish people told us was that sometimes it isn't enough to do everything right. We planned everything and did as much as we possibly could to socialize them effectively and it ended up only fine after a lot of struggle. I had always figured that people who had cats who hated each other simply didn't follow the best practices when introducing them to each other. But that's clearly not the case.
