Animal charities and local vet practices have come together in Sheffield to reduce the number of unwanted cats and kittens. The initiative responds to an eight per cent increase in cats brought to the RSPCA over the last two years, with a total of 31,000 in the last year alone. Six charities and eight vets are taking part in the project. Sheffield Live! reporter Simon Thake spoke to Carrie Stones, RSPCA cat population control manager for the north.
