Loop Through Magento Categories, Meta Keywords and Descriptions - php

Question

I have a file that is successfully looping through my categories and subcategories. I am successfully able to echo all the categories and their links
BUT
I do not understand why these (keywords and description) are not echoing
<?php echo htmlspecialchars($this->getKeywords()) ?>
<?php echo htmlspecialchars($this->getDescription()) ?>
The file is located here
app/design/frontend/mystoretheme/default/template/catalog/category/listofcats.phtml
Then im placing it on a block in a cms page {{block type="catalog/navigation" name="catalog.category" template="catalog/category/listofcats.phtml"}}
The goal is to be able to display each of the categories list of keywords and their descriptions within the same < li > and loop giving me a list like this
Category
Keywords
Description
Here is my code. I have omitted my attempts at keyword and description since they are not working.
<div class="block block-list block-categories">
<div id="block-categories" class="block-title active">
<strong><span>Categories </span></strong>
</div>
<div id="leftnav" class="block-content" style="display:block">
<?php $helper = $this->helper('catalog/category') ?>
<?php $categories = $this->getStoreCategories() ?>
<?php if (count($categories) > 0): ?>
<ul id="leftnav-tree" class="level0">
<?php foreach($categories as $category): ?>
<li class="level0<?php if ($this->isCategoryActive($category)): ?> active<?php endif; ?>">
<span><?php echo $this->escapeHtml($category->getName()) ?></span>
<?php //if ($this->isCategoryActive($category)): ?>
<?php $subcategories = $category->getChildren() ?>
<?php if (count($subcategories) > 0): ?>
<ul id="leftnav-tree-<?php echo $category->getId() ?>" class="level1">
<?php foreach($subcategories as $subcategory): ?>
<li class="level1<?php if ($this->isCategoryActive($subcategory)): ?> active<?php endif; ?>">
<?php echo $this->escapeHtml(trim($subcategory->getName(), '- ')) ?>
<?php $secondLevelSubcategories = $subcategory->getChildren() ?>
<?php if (count($secondLevelSubcategories ) > 0): ?>
<ul id="leftnav-tree-<?php echo $subcategory->getId() ?>" class="level2">
<?php foreach($secondLevelSubcategories as $secondLevelSubcategory ): ?>
<li class="level2<?php if ($this->isCategoryActive($secondLevelSubcategory )): ?> active<?php endif; ?>">
<?php echo $this->escapeHtml(trim($secondLevelSubcategory ->getName(), '- ')) ?>
</li>
<?php endforeach; ?>
</ul>
<script type="text/javascript">decorateList('leftnav-tree-<?php echo $category->getId() ?>', 'recursive')</script>
<?php endif; ?>
<?php endforeach; ?>
</ul>
<script type="text/javascript">decorateList('leftnav-tree-<?php echo $category->getId() ?>', 'recursive')</script>
<?php endif; ?>
<?php //endif; ?>
</li>
<?php endforeach; ?>
</ul>
<script type="text/javascript">decorateList('leftnav-tree', 'recursive')</script>
<?php endif; ?>
</div>

Please check this:
<?php
$categories = Mage::getModel('catalog/category')
->getCollection()
->setStoreId(Put the store id here)
->addAttributeToSelect('*')
->addIsActiveFilter();
foreach ($categories as $category) {
echo $category->getName();
echo "-";
echo $category->getMetaKeywords();
echo "-";
echo $category->getMetaDescription();
echo "<br/>";
}
?>
