Yep had that happen once crossing a bridge on my way into Philadelphia, that kitten scared the crap out of me. She hopped over the seat, under the seat, in the back window, over the front seat, you can get the visual, finally caught her, put her down my zipped sweatshirt and there she stayed until I hit the toll booth. As the toll taker was handing me back my change, kitty decided it was time to bolt. Ha, she jumped into the tolltaker's hands. The nice tolltaker got out of his both opend my backdoor, put kitty in the cardboard box, secured it, then asked me for a date. What a night!
