I purchased 5 slings about 3 weeks ago and they are doing fine. Two of them my b. smithi and n. chromatus each made themselves a burrow and I come home this evening to find that both the burrows are blocked up with a ton (well a ton to the size of the sling) of earth! Are they alright or is it some tragic digging accident? I dont want to disturb them incase they might be molting or something. The smithi has even killed the cricket I put in last night, left it, and gone. Is this premolt behaviour, just being unsocialable, or need emergency excavations? :? :?
