I am new to raising cats. I now have about 18 chrysalises in a net cage and it has been about 3 weeks. Nothing has happened, they are just hanging there. We are leaving next Wed. for a trip to Mexico and I don't know what I should be doing with the chrysalises. I have a friend coming in every day to care for my 2 Kitties but what do I tell her about the Monarchs? I am in N. TX zone 8A. Please help!
