Your using a fixed table width
<table style="border-right:1px solid #7e838c;
border-left:1px solid #7e838c;" width="760" border="0" align="center" cellpadding="0" cellspacing="0" class="border">
<tr>
You have dateformat set to the longest possible format so of course the other tables are squished.
If your not using cat avatars try turning off that table row and try shortening the date format.
With such a small site width your not gonna be able to do much if you want to show everything
