I can't choose between the two. I used to like dogs a lot more than I liked cats, but that's because my dog, Shadow, was a huge part of my life since I was four, and our first cat, Keesha, was horribly mean. She's calmed down now, and was my constant companion during my two knee surgeries over the past year. I also have been in contact with the friendliest stray you'll ever meet and two litters of her kittens. We kept two of those kittens, Kali and Chiisai, and they are the friendliest things ever. I fall asleep with them outside all the time.
So yeah, definatly can't choose. I love all animals, and none are better than others. Dogs and cats can both be very loving and playful.
