15 months ago when I accepted my fate that the Siberian I was fostering would never be leaving I bought her a bed. She of course ignored it and choose my office chair and cushion.
Thursday this week I picked the forsaken bed up from my bedroom floor gave it a poof and tidy before my cleaner came. Then later in the day I put it back where it had been previously ignored. Since then she has left the bed only to eat and use her litter tray.
It would seem a purpose bought bed needs to be ignored for a critical length of time before it can be used!
