My sister's cat had an accident yesterday and got himself trapped between the shed and a fence and was stuck for several hours in the rain. It was only pure luck that he was found. He was freezing cold and unable to walk and held his head on one side - he has a lot of symptoms of head trauma (his head was a lot lower than his body when trapped and will have had a lot of excess blood to the brain) which hopefully will not cause any lasting damage but it's too early to tell.
We whisked him to the only emergency vet we could find last night (fortunately we have one within 15 minutes who has a nurse permanently on site) and he is currently there being looked after. He was responding to light and responding to the tests she carried out (albeit very delayed on one side) but couldn't walk properly. They've got his temperature up a little bit and got antibiotics and steroids into him but he still isn't walking and is quite poorly.
Just needing some famous Purrs vibes for him
