Why Can't A Puppy Be Like A Cat?

I did it again!!! The puppy named Lotto came to our house tonight with his owner and I hissed at him. It's just the worst and I can't help myself. If he were a cat, he'd totally understand. But he just lays there and looks at me like he's hurt that I did it but he will accept my cruelty towards him. If only he would hiss back, but Tom Selleck told me puppies do not hiss. How will I ever sleep tonight feeling so bad? Oh, wait a minute, I'm a cat so sleeping is not a problem ever!
