Letter: Foxes and lobsters

Sir: By suggesting that a proponent of animal rights must consider the lives of humans and woodlice to be of equal value Alasdair Mitchell (letter, 21 July) is clouding the issue.

While the capacity of a woodlouse to suffer is open to question, the same can certainly not be said of our fellow vertebrates, so many of whom are eaten, pursued by hounds or experimented upon.
