Totally agree Renee, it was only a couple of months ago when I saw a similar thing when a cat had been hit near my house and at least 8 cars that I saw drove round it and carried on with their journey. The cat was in the middle of the road sat up but hunched over bleeding from its face. Not a pretty sight.
I pulled over as did one other and we gentally moved it to the side of the road. I saw its face and eye swell so bad it looked like a cartoon cat and chunks of blood and skin started to drip from its mouth.
We knocked on a few doors to find out whose it was as it had no collar, turned out to be a stray but an old lady had been feeding it for 8 years. The other lady who pulled over turned out to be someone who ran a shelter for cats and she boxed the poor mite and took it to the vets, never did find out what happened to it but from the visible injuries it should have been put down for the cats sake.
Not nice when things like this happen! 🙁
