Bring the cat to your vet.
Can you give a cat asprein for moderate pain?
If this has happened take your cat to the vet immediately! This is a serious injury and should be handled by a vet. The vet can clean and treat the wound. They will give your cat antibiotics to insure deadly infection does not set in, and will give your cat safe medications to alleviate pain. It is not fair to make the cat suffer by not taking it to a vet, and human pain medication is usually lethal to cats. So do not try to medicate your cat yourself.
Never self medicate your cat. Take the cat to vet for a proper diagnosis on it's paw. There could be a broken bone or an infection you can't see.
No, you can't give meds prescribed for a dog to a cat.

Take the cat to the vet. Never try and medicate a cat yourself, as it is far too easy to overdose such a small animal using human medication. A vet will be able to clean the wounds, administer painkillers and antibacterial treatment. You will most likely get a prescription of antibiotics and painkillers to give to your cat daily for a week or so to prevent infection and to help the wounds heal.
