I've never really liked rats. I can't see a point for them, although India has taken them to its heart.
There are, by the way, no cats in Bombay. Plenty of sick-looking dogs living off dust, but no cats. It's as though they got together, took one look round and said, "Fuck this, let's build a raft."
But rats - rats are everywhere. Which is a shame, as I've never liked rats. One of my earliest memories is living on a housing estate in Northampton. We'd only just moved in, so there was no furniture, and the TV just rested on the floor. I was watching Star Trek, and a rat ran in front of the screen. I've never liked Star Trek since.
The only nice fact I've ever learned about rats came from a man I met in Hyde Park. He was so remarkably under-endowed he made a cat look well-hung. I was gamely trying to go down on him on a park bench, and he just stopped me. "Never mind," he said, "Let me tell you about the Royal Parks instead."
One of the things he told me was that Hyde Park has almost no vermin, as it is large enough for foxes to live in. And foxes eat all the rats. This is the only nice thing I've ever heard about rats.
