There's a new trend in China and people are willing to fight for it — it's a Cat Paw Mug.
Offered by Starbucks for a limited time only, the campaign went viral and now there are brawls breaking out in Starbucks coffee outlets as people scramble to get their hands on one.
It's a simple, double-walled tumbler but its quirk is that when you pour liquid into it the shape of a cat's paw becomes visible.
The mug went on sale on Tuesday for about R420 ($30) and was sold out within minutes, causing the Starbucks team to re-think the campaign.
CNN reports that after the craze began and the mugs sold out, Starbucks launched an online sale.
