Choosing between dogs and cats is like choosing between apples and tomatoes.
More like choosing between apples and banannas.
I like both cats and dogs, and I got a kitten a few weeks ago, and have a 1 year and a couple months old, but also like, 4 dogs. All in the same house. They never get into fights, and to those saying all cats are pretty much lazy, the older cat plays around with this chihuahua I have sometimes, and the kitten is very curious and plays with the chihuahua too, but then again it is a kitten.
So I must say I like both. Both are playful, cute, and all that.
