Yes, Amber stays indoors at all times, unless we take her out on a leash and harness or for her car rides. As to why we have a bobcat? My wife and I breed Pixie Bobs. I don't know if anyone is familiar with a Pixie Bob, but as legend has it, they are part domestic and part bobcat. Pixies do get quite large, our male is 21 pounds. Our bobcat is not for breeding, she has been altered already. I just became more interested in bobcats after owning Pixies. There is no worry about owning one. She was not taken from the wild and they are very friendly. Bobcats tend to be more shy and are not very agressive, as compared to other wild cats. We bottle fed her as a kitten and they actually become very attached to you. They do, however, require a lot more work to take care of. They need more attention and play time and I admit, are not for everyone. You have to be very dedicated to her, almost like having children I think.
Here is another one of my Pixie bobs.
This is Little Roar
