If it helps, we had a kitty who apparently ran into a car's wheel. She was knocked out cold (we thought dead) - but she came round on my dad's knee on the way to the vet. the vet was worried she was brain-damaged as she had a bad squint - but we reassured him that she was Tonkinese & always had that squint. Then he thought she was in pain as she meiouwed all the time - again, we said that was what she always did. We took her home (after no work done) & she is now nearly 20. Also we had another cat (her son) who was hit twice. The first time he broke his pelvis & the vet said it didn't look good, but we kept him quiet & he learned to walk (again no work done). The second time he walzed up the drive all wet down one side - a driver stopped & said they had hit him. Apparently no side effects (mind you - I didn't see if the car was dented). Seriously, although we have had several kitties killed on the road - we have also had several get away scott free. They really have amazing healing powers. I hope if one of my cats is unfortunate enough to get hit, that it's someone caring like you. It always makes me feel very sad when I see a dead cat by the side of the road & think that it might belong to a little child . . .
