** 05/03/2013: Apologies to anyone who has e-mailed me over the past 6 months or so and hasn't yet received a reply. Unfortunately I have been suffering from severe repetitive strain injury and this has made it very difficult for me to keep up with e-mails as my computer use is restricted. However, I do read every e-mail that comes through and I will reply as soon as possible.
** Updated 20/06/2012: I've finally given this site a complete overhaul, with new photographs, illustrations and up-to-date information. There are a number of new sections, and all the existing pages have been completely re-done. I hope you all like the updates! Feel free to e-mail me at with any comments or suggestions. **

** One of my other hobbies is collecting old photographs of dogs from 1860 onwards. I am now making my collection available to view online - check out my blog on Facebook. And if you like my rats then check out their Facebook page - Archer and Friends!**
