I've been thinking about getting a Lookout Console for my SUV. I drive a Jeep Commander, and Lily is about 4 lbs. I'm just wondering about the sizes. There's a smaller one, and a larger one. They do list the dimensions, but I'm not sure how generously sized they are in real life. LOL.. Also, can the smaller one (that I guess is for cars) be used in an SUV? Just thought someone with experience might know.
