Well i have 3 and I love having multiple. They love to play with each other and they just adore each other. I love to watch them together. There are definitely drawbacks, but I didn't really feel that way until I got the 3rd one. My first 2 still went everywhere with me in my large Kwigy-Bo bag, with the 3rd wasn't quite so easy. That's why I'm thinking of adding 1 more to make it even again so that I can take turns taking 2 with me and nobody is ever alone.
