So sorry for your loss.
One day, we were walking and our two dogs trotted to the field they used to run on , but stopped halfway and stood over a cat.
They would not come when I called, just stood staring in my direction.
I walked up, and the cat was semi~sitting on the road ..It was a very hot day, and the cat was miaowing, loudly, With my hounds looking on, quietly.
tried to ''shoo'' the cat off the road, but he wouldn't move.
I gave him a gentle push, and felt bone move under my hand.
His gums were white.
He needed a vet urgently.
We hitched to the local vets, the three animals and me on a kindly driver's back seat.
The cat, ''Henry'' had immediate treatment due to internal bleeding and he had a fractured pelvis and femur.
The owners were so grateful, Henry had surgery and crate rest , and I was lucky enough to meet him and his owners when he was well again.
Vet said he would have died within the hour had he not been taken to a vet's.
A driver surely would have known that a cat had been hit.
They should have checked.
@cadburyegg You did all you could. I hope the cat makes it.
