A little boy was riding his bicycle in the driveway of Californian home when he was suddenly attacked by a neighbour's dog.
Luckily, Tara the family cat, came to the rescue, knocking the dog back and scaring him away.
The encounter was caught on CCTV camera and uploaded to YouTube by the boy's father, Roger Triantafilo, who said "My cat defends my son during a vicious dog attack and runs the dog off before he can do additional damage. Thankfully, my son is fine!"
The boy received 10 stitches for his wounds.
