var opts = {
  method: 'PUT',
  url: 'user/2',
  json: { kitty: cat },
  headers: {
    'content-type': 'application/json'
  }
}
 
xhr(opts, function (err, res, data) {
    if (err || res.statusCode > 299) {
      return handleXHRError(data, err, res.statusCode, emitter)
    }
    emitter.emit('user:message', 'Your password has been updated')
})
