Ujang was bought also from a pet store. We had bought him as a gift to Mila so that she has a companion. They have been staying in the same cage ever since they were small.
Ujang is very protective over Mila. In fact he is so dominant that when we had put Peter in the same cage, Ujang had bit parts of Peter's ears! No joke.
Then again, Ujang loves to bite all the other rabbit's ears. He has a fascination for ears I reckon. This is also mum's rabbit.
