2) Cats are not as solitary as you think. Yes, they don't live in groups usually, but that doesn't mean they are not affectionate. They just are not as boisterous about it as dogs nor do they depend on it as much as dogs. Therefore, respect your cat's need for alone time but don't be surprised if it a little pissed after you been gone for a while .
3) Another tip for dogs owners: don't let your dog sniff the cat's butt; it drives them crazy. Cats only greet nose to nose.
4) Cats are adaptable but don't like too much change in their enviroments. This is probably why cats don't travel well.
