Our stud Fionn (Fionn van Scarlettini) lives together with spayed Dewi van Scarlettini and then and when also has the company of Sailon, Neito, 
Kumari and Rukmini.

They live in a separate part of our house which we call 'the apartment' as the former inmates let this part. Fionn and his girlfriends have the kitchen and the bathroom at their disposal and a cat flap in the window gives entry to their outer run.

When we come home Fionn is always there to welcome us.

Till Galaxy's decease,  9 september 2008,  Fionn and he lived here together.

As the window is in a high place there is a climbing pole resisting atmospheric action which they can use as a step.

In case you want to see how the outer run was built:
