I wanted to kill the fucking cats I lived with last year. The stupid bitches shited in my plants, drank out of the fish bowl, barfed all over the place, bit and clawed my guests, ripped my bed into shreds, and taunted Dakota (which would explain his current habit of barking and growling).
That being said, the huge German shep/Austrialian cattle dog mix I lived with was a wonderful dog, but it was a trial always taking him outside to so his business. Which is why dogs aren't the best pets if you live on the third-floor of an apartment.
Now, some stupid-ass cat gave birth to two kittens on my sister's front door, and she took them in. Since I was the 'animal person' by working at the vet's office, I ended up feeding them and making sure they relieved themselves. They're well-behaved, quite, and non-destructive. I tolerate them.
Basically, I can't stand cats or little yappy dogs. Currently, I'm looking at Russian wolfhounds, Irish wolfhounds, bull terriers, mastiffs, or airedales as potential purchases once I'm able to take in a dog.
