Here Is Why You Should Never Install a Cat Door [VIDEO]
Cats do not care what you think. They don't care about your feelings, they don't care about all the time you spend thinking about them, they don't care about all the little things you do for them. Except feeding them, of course, they do care about that. And changing the litter box. But honestly, they'd get along just fine without you. They're cats.
Speaking of cats, some poor guy spent an hour-and-a-half installing a cat door for his feline, Philo, so Philo could "come and go as he pleases." A very thoughtful gesture, but apparently this guy didn't remember that cats don't care. Philo certainly could use the cat door his owner put so much effort into constructing, but would he? Of course not. Of course Philo already knows how to "come and go as he pleases." He's a cat.
One last time: cats don't care. Don't spend an hour-and-a-half installing a cat door. Just don't.
