This is an overdue update:
Lovely Beverly has passed over the rainbow bridge in Sep/Oct. She will, of course, be longer homeseeking.
Bonnie, whom Foster Mum calls Yo Yo, will become a permanent resident at the cattery. This is because, with time, her character shows her to be in need of a garden to roam in.
She also does not bond easily with people, though she is very attached to Foster Mum and her helpers. She is one cat who will definitely need extra time and attention to adapt. So Foster Mum has decided to keep her.
