Cat Nail Punture
Nail punctures (or any punctures) are dangerous and should be treated by the vet. Punctures close up quickly, thus permitting tetanus bacteria to go to work.
If a veterinary surgeon is available, take the cat to him right away. If not, you must clean the punctures. Restrain the cat. Wash the punctures with soap and warm water. Open up the punctures in order to soak the wounds with soap and water. Apply an antiseptic, working it into the punctures. Get the cat to the vet as soon as possible.
