A litter of kittens fell from a tree after the mother gave birth up in the branches.
The RSPCA rescued the feline family of five after several people spotted the newborns had fallen from the foliage.
The tiny black kittens were taken into care at RSPCA Putney Animal Hospital, but sadly one died overnight.
RSPCA inspector Phil Norman attended the rescue in Standard Road, Hounslow on Tuesday (August 1) evening.
He said: “We believe the mother had given birth up in the tree where she felt safe and secure and away from any danger.
“But for day-old kittens to be at such a height is obviously potentially very dangerous and three of the four babies had actually fallen from the tree.
“Thankfully, they weren’t injured and we could hear the fourth kitten squeaking so we managed to find them all before catching mum who was quite nervous.
“It’s sad that one of the little kittens didn’t make it but I’m really pleased that the mum is doing well and the other three seem to be feeding well."
The charity has put up posters in the local area in the hope of finding the owner.
However if no-one comes forward then feral cat nicknamed Twiggy, and her kittens Willow, Ash and Oakley, will need to be rehomed once they are weaned and old enough.
Until then they will be cared for by the RSPCA.
Inspector Norman added: “It’s amazing really that these kittens were spotted and weren’t seriously hurt. They were very young and vulnerable, probably only a day or two old, and their eyes were still closed.
“One of them was still attached to the placenta and was very precariously hanging from a branch when I arrived, and the others had all fallen from the tree and were left lying on the ground and in nearby bushes.
“Thank goodness the people who spotted them acted quickly and got in touch with us.”
