Hi Aileen!
I just changed the code for the white angel kitty. It seems to work in IE. In Firefox it shows on the top part of your page and will disappear if you scroll down.
I'm going to keep testing things before I change the code for the other scripts that float upwards.
You can keep using the angel kitty code that floats upwards:
<script language="JavaScript" src="http://www.twilightmoon.net/cc/js/angel.js"></script>
Or you can also have angel kitties that fall like a regular falling object script:
<script language="JavaScript" src="http://www.twilightmoon.net/cc/js/angel_down.js"></script>
