Why I hate cats:
They crap in a box in your house that makes the entire house smell like crap.
Why I hate cats:
They crap in a box in your house that makes the entire house smell like crap, they don't do anything you want them to, they vomit hair balls every other day, and they think they're head of the house. Dogs are where it's at.
Like Speedy said, you have to clean the box just like your supposed to clean up the dog's **** if it's on your lawn unless you're a lazy prick.
Cat's will respond to you if you give them the proper amount of attention if you raise them right.
If they vomit hairballs all the time, you should brush their hair and/or have them checked out by a vet. Also make sure they don't eat too much.
Cat's are territorialy and if you train it correctly, they won't act like "the head of the household".
What you are complaining about is the same for dogs if they aren't cared for properly.
I love both cats and dogs and some of them have issues but that's on the owner.
After a cat ruins your rentals, even though they are not supposed to be there, you loose the love. Outdoor cats are alright I guess as long as they are fixed. I have a husky named Poncho that is smarter than any cat. You forgot everything is a scratching post.
