is ur cat have a little bit problem at outdoors..

Cats can be trained a little at a time, they need a place where they feel safe to go to and then check up the surroundings when they feel they want to do it. Just be happy that your cat is careful, it will save it from many dangers. Cats are very curious so if you leave the door open in the beginning so that the cat can go in again if he feels insecure, he will start to explore the outside - no need to hurry. When you introduce new people, let the cat take the initiative to go close to the person, that will work best. Their natural curiosity takes over.
