The cat is independent. It is a MGTOW sort of a beast.
The dog is approval seeking and is at a loss when its master leaves the house. A dog is like a Social Justice Warrior.
Nobody owns a cat. This is even recognised in law. If a dog bites a stranger the ovner is liable for the injury. If a cat scratches someone then nobody is to blame because the cat has no owner. It remains a wild animal.
Why is the cat so free? It owns nothing- yet it enjoys everything.
Be more cat.
