A serial cat killer in South Wales appears to have struck again just a few miles from where eight pets mysteriously died in the summer.

This time four cats are suspected to have been killed after drinking poisonous anti-freeze left out for them in Caldy Close, Barry, according to The Sun.

It follows the first eight cats dying of the same cause in Underwood Place, Bridgend, some 10 miles away, in July and August.

The latest cats, in neighbouring households, died between September 29 and October 6.

Stephen Griffiths, 25, and his girlfriend Sarah Jones, 32, lost their pets Sugar and Pudding.

Mr Griffiths told The Sun: "It is horrible to think how they died.

"Even now I go out into the garden and expect them to come over the fence. But then nothing."

Ms Jones said children Morgan, four, and Riley, two, had been particularly upset.

The other two cats, Charlie and Phoebe, belonged to a neighbour who did not want to be identified.

A vet said all four animals died of kidney failure, brought on by ingesting anti-freeze. The liquid attracts cats because it tastes sweet, but is highly toxic.

Christine McNeil, an RSPCA inspector, said: "We would like the public to help us. It is likely that someone may have seen someone acting suspiciously."

Anyone with information is asked to call the RSPCA 0300 1234 999.
