Call pull feeds function: /controllers/feeds_controller.php

<?php
var $components = array('Twitter');

function get(){
$feed = $this->Twitter->parse_cache_feed('TWITTERNAME',10);
$this->set('feed', $feed);
}
?>

Auto-refresh function: /views/feeds/index.ctp

<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js">
</script>
<script language="javascript">
 $(document).ready(function (){
 $("#twitter").load("/feeds/get");
 var refreshId = setInterval(function() {
 $("#twitter").load('/feeds/get?randval='+ Math.random());
 }, 300000);
 });
</script>
<div id="twitter"></div>

Display Feeds: /views/feeds/get.ctp

<?php
for($i=1; $i<=count($feed); $i++){
 echo $feed[$i]['content'].'
';
 echo '<a href="http://twitter.com/TWITTERNAME/statuses/'.$feed[$i]
['id'].'">'.$feed[$i]['date'].'</a> · <a href="http://twitter.com
/?status=@TWITTERNAME%20&in_reply_to_status_id='.$feed[$i]['id'].'&
in_reply_to=TWITTERNAME" target="_blank">reply</a>';
