Sister of Bibby, and daughter of Lucky, Zorro developed a melanoma on her nose which has developed into a huge tumour; she will shortly be sent to "cat heaven".
Update: regrettably, by my own intervention, I had to put Zorro to sleep this afternoon (15th June 2009). We were unable to get her to the vet for painless euthanasia and I could not bear to see her suffer any longer - her end was as quick and painless as I could make it. A very brave little cat.
