This is a template for Microsoft Excel (2002) which can be saved onto your computer to create a printable family tree for your rats (or other pets). To save correctly, right-click on the image or text link below and choose 'Save Target As...' (in Internet Explorer) or 'Save Link As...' (in Firefox). You will be able to open it to view online with IE without saving first, but don't fill it in online as you may find it impossible to save the result.
The file contains two worksheets; a four generation sheet and a three generation sheet. This template may be copied and redistributed freely.
I also have a page which will produce an html family tree to use on your website.
