Two cats, including one which is pregnant, were tied up a in a bin bag and dumped outside a Peterborough home as temperatures soared.
The black cat and pregnant tabby and white cat were found by a woman outside her house in Bourges Boulevard who thought someone had wrongly delivered something to her.
The cats, who have fortunately not suffered any ill-health, have now been taken in from Daphne Wilson at Peterborough Cat Rescue.
She said: “Something has got to be done to stop all the breeding of cats or they will become vermin.”
