We were pleased to see our first slow worm -- a female about 10 in. long -- on the move in our garden yesterday. However, after settling itself in the sun under some magnolia petals, we noted that it had stopped moving and stayed put until nightfall. We took it inside in a box with leaves and a dish of water, but it hasn't moved since. The box is now outside with a large hole cut so that it can exit, temperatures are between 11 and 15 degrees, and the worm hasn't changed at all in appearance -- It's still lustrous and is not flaccid when touched, and it's eyes are closed. Could it have slipped back into hibernation mode?
