Like people, cats grow through several life stages:
- Young adult
- Mature adult
Just like people, you need to train them early so they grow up with the right habits. Especially when felines are kittens, you can identify normal behavior and identify potential problems so you can cut them off before they get out of hand (just like teenagers).
Even if your cat is no longer a kitten, you can still deal with its behavior to shape it the way you want, which typically means letting the cat do what it wants and getting out of its way.
