If it hadn't been for the squirrels, George Matthew's attempt to become a cocoa bean producer might have failed.
His farming career began in the 1970s when he inherited a rubber plantation in the the southern Indian state of Kerala , which he managed alongside his career as a doctor.
It was a bad time to inherit a rubber plantation, falling rubber prices meant it kept losing money. So, 10 years ago Dr Matthew decided to experiment with cocoa trees, hoping they would generate some funds to support the rest of the farm.
He bought some saplings and planted them. It didn't go well.
"It was not that successful - most of the saplings died," he says.
Squirrels appeared to be making the situation worse by grabbing cocoa bean pods and eating them.
But those raids had an unexpected benefit - cocoa seeds were spread all over the farm.
"All the scattered seeds soon grew in to plants and they were much healthier and stronger than the saplings I had planted," says Dr Matthew.
"The trick was in sowing the seeds," he realised.
Today Mr Matthews has 6,000 cocoa trees on his 50 acres of land.
"I think it was the best decision I have made," he says.
