AngularJS not parsing valid JSON

Either I'm using the $resource incorrectly (most likely, just started with angular today) or my JSON is bad.

AngularJS fiddle: http://jsfiddle.net/8zVxH/1/ and relevant code:

angular.module('app', ['ngResource']);

function AppCtrl($scope, $resource) {
var url = 'http:,,api.petfinder.com,pet.getRandom;key=260f9e3a6f6670b5d9db68b281ebe7a9;format=json;location=51503';
$scope.petfinder = $resource('http://jsonproxy.aws.af.cm/proxy/:action', 
                                 {action:url, callback:'JSON_CALLBACK'},
                                 {get: {method:'JSONP'}});

$scope.indexResult = $scope.petfinder.get();

}

jQuery Fiddle:http://jsfiddle.net/78Cab/ and relevant code

$.ajax({
  url: 'http://jsonproxy.aws.af.cm/proxy/http:,,api.petfinder.com,pet.getRandom;key=260f9e3a6f6670b5d9db68b281ebe7a9;format=json;location=51503',
  method: 'GET'
}).done(function (data) {
  console.log(data);
});

the jQuery fiddle works hitting the same URL..

Hitting this JSON URL http://jsonproxy.aws.af.cm/proxy/http:,,api.petfinder.com,pet.getRandom;key=260f9e3a6f6670b5d9db68b281ebe7a9;format=json;location=51503 which passes http://jsonlint.com/ as valid JSON

Anyone else have a similar issue?
