SIR, I am writing to invite your animal loving readers to host a Paws for Tea tea party on Friday 15th May in aid of the wonderful work of the Blue Cross pet charity. Blue Cross's Paws for Tea fundraising event combines the nation's greatest loves – tea, cake and pets. To take part, all you have to do is hold a tea party with friends, family or colleagues and ask them to make a donation in return for some tasty treats.   As an owner of many much loved pets, I know first hand how rewarding they are and how much joy they bring to our lives. But sadly not all pets are fortunate enough to have loving homes. Blue Cross works tirelessly to help over 40,000 sick, injured and homeless pets every year that would otherwise have nowhere else to go. All funds raised will help Blue Cross care for the country's most needy pets, and every penny raised really does count. So go on, put the kettle on and sign up now at http://www.bluecross.org.uk/teaparty">www.bluecross.org.uk/teaparty or phone 0300 790 9903. Martin Clunes (Blue Cross)
