Cows in Varanasi are very common. It’s more common than running into a Zubat when you’re playing Pokemon and are exploring a cave. The problem is, there are very few naturally-occuring plants that can feed the gentle giants. So as common as it is to see a cow walking around, it’s almost as common to see the cow sniffing and licking its way through trash to find whatever food scraps it can. Some people feed the cows roti (bread), and even some feed them subzi (vegetables). Our leftovers from the night before happened to be a perfect nighttime snack for this little fellow.

It makes me feel sad to think of these lovely animals having to trawl through trash just to eat, I didn’t know this was the case but I am not as well travelled as you. I can’t imagine seeing a cow scoffing from a rubbish bin over here in the UK. I am pleased that you fed the little fellow 🙂
