1. Snowball: in contrast to "briquettes" , one black and one white, both vivid and interesting.

2. Hanamaki: If the other cat’s coat color is patterned or striped, this name will be very appropriate.

3. Pudding: A cute and warm name, suitable for cats of any appearance.

4. Pom pom: Emphasizing the softness and cuteness of the cat, it is also similar to "briquettes".
