I have an A. avicularia sling that's a little over 1cm DLS and as far as I know they are supposed to be heavy webbers? Mine has not built a web at all, and it hangs out at the top of the enclosure a lot (which is normal) BUT, I got this sling like 6 weeks ago and it hasn't eaten at all. I can't tell if it's in premolt but it's abdomen does not look shiny to me. Is my avic unhappy? I attempt to feed it once a week but it has absolutely no interest in food and it's abdomen is small. Suggestions?
