She is 3. I'm not sure exactly when she was spayed as she was from a family friend but I assume at about 6 months. She definitely was though (they are very good friends and wouldn't be mistaken), plus she is perfect with her litter tray.
She was being bonded with my pair until they fell out last week, she is now by herself again and I imagine it may have been a very stressful time for her. She's chilling with me in the lounge at the moment, I'm hoping a bit of love might help, she loves human company.
