The rise in the popularity of the selfie is turning out to be bad news for black cats.
Increasing numbers of the felines are being abandoned in Britain, and the RSPCA thinks it is partly because they do not photograph well.
More than 70 per cent of the 1000 cats in the organisation's care are black and a spokesman said it was struggling to find new homes for them.
That was partly because of the difficulty photographing black cats, making owners less likely to engage with those animals in online profiles.
In British folklore black cats symbolised good luck but in reality they were not so lucky, he said.
"There are a number of reasons for this, ranging from the fact that black cats are harder to tell apart than cats with more distinctive markings and the fact that black animals tend not to photograph as well."
Ronnie McMillen, founder of the Millwood Cat Rescue Centre, told The Telegraph the facility was "full to bursting".
"We have had a lot of black cats in this year. People don't like black at the moment."
