I have two 5 month old rabbits that are in the ground cages that are part chinchilla part dwarf of an unknown breed but they show no sign of dwarfism, they are large bunnies.
I also have two 10 week old rabbits that are Chinchilla, California, New Zealand, Sable Martin cross. They are playful, friendly and well socialized. They have fabulous personalities that would be perfect for a pet.
