People have demanded answers to these questions since 1979, when Nancy Wertheimer, an epidemiologist, wrote a paper with Ed Leeper, an independent physicist in Boulder, Colorado, purporting to show that children living close to power transmission lines were twice as likely to
contract leukaemia as children in homes farther away.
Neutered cats are at less risk from Feline
Leukaemia Virus (FeLV) or Feline Immunodeficiency Virus (FIV) which can be
contracted through fighting with other cats.
