For a Cat Tree

1. It gives the cat somewhere to scratch other than the arm of the couch.
2. It'll help the cat burn some of his energy.
3. It gives the cat a safe place to sleep, away from children.
4. It provides a place for the cat to put all her toys.
5. It has places for all the kitties, though they'll always fight one one spot.
6. It lets the cat look down on all his subjects from on high.
7. It proves that the cat is more important than the dog, as all he got was a fluffy bed (which the cat has also claimed).
8. It is the perfect place for the cat's human to distribute treats.
9. It is a great place to go when the cat is upset with his human, seeing as the human cannot climb to the very top.
10. It allows the cat to practice their fighting skills on something sturdy.
