How to recombine key and value into an object?

In my Angular app, I am using ng-repeat to cycle through all the items in a JSON object I have. So for example, for my JSON object:

$scope.animals = 
{
     horse: {
          sound: "Nay",
          legs: 4,
     }
     beaver: {
           sound: "thwack",
           legs: 2
     }
}

I want to cycle through to get a list consisting of Horse, Beaveri.e.

<div ng-repeat="(key, value) in animals">
     <div class="niceBox">
          <h1> {{key}} </h1>
     </div>
</div>

but for each animal, I want to have a button that takes the whole object and adds it to a list of my favorite animals. Something like this:

<div ng-repeat="(key, value) in animals">
         <div class="niceBox">
              <h1> {{key}} </h1>
              <div ng-click="addToFavorites(animal)">Add To Favorites</div>
         </div>
    </div>

The Trouble Is that I can't just pass animal as a parameter since I broke up the ng-repeat into (key, value) already.

How do I reassemble (key, value) so I could use the object as a whole?

Your question is misleading, because there's no original "object" you want to re-assemble - there's just property names and values. If you had a single object for the animal in the first place:

var animals = [{
    name: 'horse',
    sound: ...,
    ...
}, {
    name: 'beaver',
    ...
}, ...];

there would be nothing to "re-assemble", you'd just use it:

<div ng-repeat="animal in animals">
    {{animal.name}}
    <button ng-click="addToFavorites(animal)">...</button>
</div>

Try by this this

<div ng-repeat="(key, value) in animals">
     <div class="niceBox">
          <h1> {{key}} </h1>
          <div ng-click="addToFavorites(key, value)">Add To Favorites</div>
     </div>
</div>

And in your controller

$scope.addToFavorites = function(key, value) {
   $scope.animal = {};
   animal[key] = value;
   /** your code **/

}
