I want to ignore a cat in need of help. I just don't have the stomach for helping it.
That's not nice. Is the cat you want to ignore hurt?
Yes, he is injured and bleeding.
If you see an injured cat, you should help it rather than ignore it. Taking it to a local animal clinic could help save it's life.
It's not like I can help him.
You could help him a lot by taking him to a vet or human society. Just carefully wrap him in a towel first. A lot of veterinarians are understanding when people bring in animals like this.
