Cat's are quiet, sleep often (I think), which can be good if you want a pet that's kind of out of the way, but not good if your looking to play fetch with your pet. And if you are allergic to them, that's no fun.
I have 5 cats, one has only one eye, but it plays the most, if i knock on my glass door they all come to me! Opening that door is a cranky sound to me, but they understand it as leftover junk!
Does anyone remember the movie funny people? The Youtube video the one character uploads saying any video with cute cats and cute music gets a bunch of views.
While I love cats, and dogs, and pretty much all animals, I believe some people take it too far. People that take their pets for spa visits and buy clothes for them are just a lil strange.
