I don't know Mr Lizard Lover (personally I think Sue meant that as an AOL screen name and not really that he had his name changed) but I am sure a fish based cat food is probably loaded with nutrients and would substain a reptile if you could get it to eat it (personally wouldn't do this as I think the cat food would smell worse than our cricket bucket <img src="http://www.faunaclassifieds.com/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

Not saying it's right but that there is a school of thought out there leaning that way. Compared to other domesticated animals, reptile husbandry knowledge at a "pet" level is minimal and there is a lot of conflicting data. You really have to use common sense to wade through all the information. If your at the novice level it's safer to go with the standards of husbandry but as you gain experience you can start studying new methods and experimenting.
