Cristiano Ronaldo's pet cat is down to 8 lives ... it's currently recovering in Spain after being hit by a car.

The animal, Pepe, is a hairless Sphynx cat -- the beloved family pet who travels everywhere with the Ronaldos on private jets, fancy cars and stays in mansions all over the world. Pepe has been a part of the Ronaldo family for about 2 years.

But, Pepe was badly hurt recently -- after leaving the family residence in Turin, Italy and getting run over by a car.
