Angular-JS: ng-repeat multiple times without having a nested structure

Is there a way for me to do a nested ng-repeat call, but not having it create a nested structure.

I.e.

Say I have this in my script:

$scope.animals = {
      dog : {
        rupert: {
          size: 'big'
        }
      },
       cat : {
        jon: {
          size: 'small'
        },
        don: {
          size: 'small'
        }
      },
       pig : {
        mike: {
          size: 'big'
        }
      }
    }

and this in my html

<ul>
   <ul ng-repeat="(type,animal) in animals">
      <li ng-repeat="(name,description) in animal">
        <span>
          This is {{name}} the {{type}}, he is really {{description.size}}.
         </span>
       </li>
    </ul>
</ul>

Here is a plunkr : http://plnkr.co/edit/BtAIejohzzVjrwWDfBWK?p=preview

Basically at the moment this creates something like this:

<ul>
    <ul>
        <li>
            <span>
                This is don the cat, he is really small.
            </span>
        </li>
        <li>
            <span>
                This is jon the cat, he is really small.
            </span>
        </li>
    </ul>
    <ul>
        <li>
            <span>
                This is rupert the dog, he is really big.
            </span>
        </li>
    </ul>
    <ul>
        <li>
            <span>
                This is mike the pig, he is really big.
            </span>
        </li>
    </ul>
</ul>

I'd like it to make something like this:

<ul>
    <li>
        <span>
            This is don the cat, he is really small.
        </span>
    </li>
    <li>
        <span>
            This is jon the cat, he is really small.
        </span>
    </li>
    <li>
        <span>
            This is rupert the dog, he is really big.
        </span>
    </li>
    <li>
        <span>
            This is mike the pig, he is really big.
        </span>
    </li>
</ul>

So is there a way to formulate this to get this result, do something of this sort (this doesn't work lol)

<ul>
    <ng-repeat="(type,animal) in animals">
        <li ng-repeat="(name,description) in animal">
            <span>
                This is {{name}} the {{type}}, he is really {{description.size}}.
            </span>
        </li>
    </ng-repeat>
</ul>

*note I'd like to avoid doing this

<ul>
        <li ng-repeat="(name,description) in animals.dog">
            <span>
                This is {{name}} the dog, he is really {{description.size}}.
            </span>
        </li>
        <li ng-repeat="(name,description) in animals.cat">
            <span>
                This is {{name}} the cat, he is really {{description.size}}.
            </span>
        </li>
        <li ng-repeat="(name,description) in animals.pig">
            <span>
                This is {{name}} the pig, he is really {{description.size}}.
            </span>
        </li>
</ul>
