I fed Anansi another large cricket today, while my best friend was here. Shortly after she snatched the cricket, I dropped some water (I often use a medicine dropper for this) onto her dirt, close to a corner. It puddled up a bit at first, as usual. After holding on to the cricket for a while, she usually lays a very thin web before eating. This time, she let go long enough to take a slow drink, I guess. She left the cricket under her abdomen. It was a little weird, but I guess she was thirsty.
Anyway, there you have it. Update posted.
