I think the biggest reason ur dad doesn't want rabbits in the house, is because of their smell, when indoors they tend to stink up the house pretty good. My friends own a farm & when they were younger they raised rabbits. They had an outdoor pen, which they would put some of the rabbits in during the day & but then in a barn room for the night. the rabbits seemed happy there, they had plenty of food, a large room to run & hop around, other bunnies to play with & a ton of hay. They even had half wild & half tame rabbits, meaning some of their rabbits got lose & they still came back for food, to be played with & breed, but they lived in the wild.

This is what their outdoor cage looked like
