Cats Protection have given advice below - neutering and microchipping pets is vital. The Mayhew Animal Home has also given information on the homeless animal crisis showing that it doesn't make sense to breed more animals when there are so many homeless cats and dogs already. List of animal rescue places here here for anyone interested in giving a home to a cat, kitten, dog or puppy.
Stokey Cats and Dogs are a local volunteer group who help pets and stray cats in the community and are also a useful source of advice and help in respect of cats and dogs. They help stray cats and get them neutered, microchipped and rehomed. They also rely on and welcome funds donated by the community through their fundraising here
