Why is Zoë called ‘The Fluff’?

Zoë is the only kitten of her litter who did not have short hair, but rather medium hair.  Her fur is about twice as long as Izzy’s. Before Izzy and Zoë got their final names, Zoë was referred to as ‘the fluffy one’ to keep them apart. This nickname stuck. However, she also goes by ‘Queen of Hearts’, due to the heart-shaped marking on her chest.
