When we arrived home late yesterday afternoon we went out into the garden to check things and found the little fellow below under the garden seat. I'm calling him a 'he' he could of course be a 'she' but who knows.
He wasn't moving except for shuffling his back paws and wafting his tail over his head. Our cats were watching from a distance but didn't seem too concerned about getting close to him. He was shuddering slightly and seemed anxious and a bit dazed.
We brought him a little bowl of water and a few peanuts and sunflower hearts and left him alone for a while but he was still quite distressed so we decided to give him a quick check to make sure he didn't have any injuries, though I'm not sure what we would have done if he'd had any!
He didn't much like being held in a gardening glove - well would you? There were no visible injuries so we left him alone again and after a while he started to move about a bit - we were watching for other cats around the garden as at this point ours were being kept inside just in case - eventually he started to hop about then run a little and finally he disappeared. I think I've seen him around this morning so he seemes to have recovered from whatever trauma had affected him. Here's hoping anyway!
