Vets have dressed a pair of kittens in unusual outfits in a bid to stop them suckling each other in their sleep.
George and Elton were put into babies' socks to stop the habit which was making them sore.
The pair were just a few weeks old and barely alive when they were found abandoned in a shed in Osterley, west London on August 1.
They were taken to the RSPCA's Putney Animal Hospital, but vet nurse Katrina Devita has been hand-rearing them at home because young animals can find hospitals too stressful.
Sian Anderson, a clinical manager at the hospital, said: " You may wonder about the outfits. Unfortunately these two naughty boys have a habit of suckling each other in their sleep and making themselves sore.
"Our nurse came up with these fabulous outfits to help stop the habit. They are made from babies' socks as they really are that small. As you can see they are very happy and not affected by them."
George and Elton have to be fed by hand every two hours because they are only one month old.
They will be available for re-homing in around a month and will have to be kept together because they are so close.
The RSPCA is urging people to adopt a kitten rather than buy one.
It has taken in 14% more abandoned, neglected or sick cats so far this year compared with the same period 12 months ago.
In 2014 it has rescued 3,306 abandoned cats and helped 7,914 sick or injured cats.
Ms Anderson said: " We are seeing such a high number of kittens coming into our care, and we would like to urge people to remember to get their cats neutered to try and avoid unwanted litters of kittens.
" Hand-rearing is so time intensive and our staff are overwhelmed by the sheer number of cats and kittens that need our help."
