Engadget has an interesting article up about creating fur for Zootopia. Apparently the amount of fur each character has climbs easily into the millions!

The software helped shape about 2.5 million hairs on the leading bunny and about the same on the fox. A giraffe in the movie walks around with 9 million hairs, while a gerbil has about 480,000 (even the rodent in the movie beats Elsa’s 400,000 strands in Frozen).
