Magento: Get sub categories and product count

Here, I will be showing you the code to get sub categories of a particular category and the number of products (product count) present in the sub categories.

Like, I have a category named Furniture. The sub categories under Furniture are Living Room and Bedroom. Now, I want to show the sub categories under Funiture and the products associated with the sub categories (Living Room and Bedroom).

Furniture
- Living Room (4)
- Bedroom (2)

/**
 * get current category
 */
$currCat = Mage::registry('current_category');

/**
 * get sub categories of current category
 */
$collection = Mage::getModel('catalog/category')->getCategories($currCat->getEntityId());

/**
 * looping through sub categories
 * only showing active sub categories ($cat->getIsActive())
 */
foreach($collection as $cat) {
 if($cat->getIsActive()) {
  $category = Mage::getModel('catalog/category')->load($cat->getEntityId());

  /**
   * getting product collection for a particular category
   * applying status and visibility filter to the product collection
     * i.e. only fetching visible and enabled products
     */
  $prodCollection = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($category);
  Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($prodCollection);
  Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($prodCollection);

  ?>

  <a href="<?php echo $category->getUrl() ?>"><?php echo $category->getName() ?></a> (<?php echo $prodCollection->count() ?>)<br/>

  <?php
 }
}
