I think cats are wonderful! I have a cat that we've had since he was born, and he is the loviest thing I've ever seen or had. He is always down for a pet and snuggle...I say he has a one-touch motor because he usually starts purring as soon as you touch, sometimes just when you call his name. I also have a teacup Yorkie that is completely attached to me and is content to just lay snuggled next to me, and loves to have his chest rubbed. They aren't service animals, but they do make me feel a little better. And they don't take up too much room.
