Rats That's what Kapuku are! If you fancy a diet of rats, you'd probably get to buy it in Lilongwe, Malawi. where you can get the rodents ready cooked, salted or dried. These gray field mice are popular Malawi delicacy.The mice are hunted in corn fields after the harvest when they have grown plump on a diet of grains, fruits, grass and the odd insect. Doesn't really look like a dirty meal, does it?
