We've had our house bunny for well over a year now. We got him as a baby and he was hand raised. So he is extremely friendly. He does go outside during the day into his hutch/cage thing. When we are home he will either be there, or inside, or outside hopping around with us in our enclosed yard (he loves that the most). He has his own little areas in the house that he can retreat to away from the kids and feel "safe" they know not to chase him into there. They've also been taught to never try to pick him up - thats the number one cause of injuries and death in poor little bunnys, so its just a blanket no rule in our house as far as kids are concerned.

Cords we dont really have a problem with, he has never ever shown interest in them and because his teeth are deformed (require hand cutting every few weeks) its almost impossible for him to chew through them anyway. I suggest you either keep them up and away from bunny or only let him out fully supervised.

Ours sleeps inside in a different cage/house that he loves, they can be sensitive to extreme changes in weather so where we live this is the best option anyway. Though he can get out of it if he is really determined lol. Because the cage is cleaned regularly he doesnt smell the house either, nor does he attract other rodents.

Our bun also house trained himself. They dont generally like being dirty so will naturally look to keep things as clean and separate as possible. We found his favourite place to go and then put a tray there, then after a while moved the tray slowly and volia he changed his spot.

He is very comfortable with us and will actually sleep on his back in front of the heater in the middle of winter lol! Thought he was dead the first time he ever did that! He is also neutered to keep his lovely nature. We joke that he thinks he is a dog he is just that well natured and friendly. The dog you have when you cant have a dog. Look at me waffling on hehehe. We obviously love our Bunny and would recommend one to most people
