If you are looking for a new pet then please consider contacting a local rescue center before apporoaching a breeder. I foster mum's and kittens from the Celia Hammond Trust who always need homes for all sorts of cats and dogs. Please check out her web site below.

If you have lost your dog or cat then you can see if they have been found on the following sites. If your pets are microchipped then they are usually returned to you within 24hrs. It is cheap and easy to do via your vet and well worth the peace of mind.
