I love cats, but I’m allergic to them and end up sneezing and short of breath if I get their hair on me. Which is why the news of hypoallergenic kittens appeals. On the other hand, having paid two and a half grand for Tiddles you’re unlikely to let it do all those independent things that make felines so arrogantly endearing in the first place.
I missed the other three episodes, but the last edition of Driven by Oil on Radio 4 covered possible solutions, including Sweden’s biofuel drive and the plant that renders turkey guts down to their constituent hydrocarbons. You can use the listen again facility to hear the programme.
