Firefighters rescued and revived four kittens trapped in a flat fire on Butler Road in Willesden, this morning.
The crews rescued the kittens which were in a basket in the property's kitchen. They then revived them using a small oxygen mask.
A man escaped the fire before the arrival of the Brigade and fortunately was uninjured.
The fire affected a five room flat on the first floor of the block and part of the property was damaged by the blaze.
Station Manager John Ryan who was at the scene, said: "Crews worked hard in really quite arduous conditions. They gained entrance to the property through the balcony and quickly dealt with what was a very, very hot fire that had built up."
Four fire engines and 21 firefighters and officers from North Kensington, Willesden and Park Royal fire stations attended the incident.
The Brigade was called at 0851 and the fire was under control at 0950. The cause of the fire is under investigation.
