I've been trying to spot this too, but it's just too cloudy right now. I've got my fingers crossed for clear skies.
That is sad news about the cat. We had a young boy that suddenly developed temporary paralysis in his back legs. We would often find him stuck outside, eventually it would ease and he was fine, but then it would occur again on another day. He must have injured his spine somehow. Eventually he had to be ‘put to sleep’ at the vet. P.S. It's fun to hear how you like driving round roundabouts!
Great photos of Neowise; I've only caught sight of it once.
