Topaz (the grey male cat) and Tilly (the black female cat), were born together. In this photo, they are both 11 years old, they grew up together, and have never been separated. Tilly is a nervous, scatty cat, while Topaz is the opposite and has a calming effect on his sister. Often they could be found together, sleeping, with Tilly cuddling right up to Topaz who puts a paw on her!!
