Oh, a little FYI. I got really paranoid about what I was feeding the Pipevine ST cats so I took out the Trilobed Pipevine and replaced it with the Wooly Pipevine. I figured I had lost caterpillars on the Trilobed, even though we've used it successfully at MOSI so I figured why not give the Wooly Pipevine a chance. So far, so good!
