Train them as we might, our pets are animals, and animals will do whatever the heck they wanna do. They can't help it. The curiosity is overwhelming. Our cats simply must find out if our favorite plant makes a good chair for them, and our dogs have to - they have to - find out if our couch is delicious. Answer: it is, that's why they keep eating it.
And yes, we still love them, of course we do, and at the end of the day, we know that we prefer them untamed and being total weirdos. Because even though they're the most kind and loving little beings, on top of almost everything else, they are entertaining to a painful degree, and that just makes us love them even more.
