Fur left behind by the long-haired Mimi has aggravated the allergies of some library users and has resulted in the the cat being given her marching orders.
She will move to a new home in Northeast Valley tonight.
Since the then heavily pregnant cat was dumped at Orokonui in December 2005 she has lived in Mosgiel and Warrington before settling in Waitati last year.
The former Warrington School cat soon made the library her new home, much to the delight of residents - or at least most of them - librarian Louise Booth said.
Ms Booth's home was one of three in the area Mimi would also visit, but the librarian said it was impossible to keep her from returning to her favourite place - the library.
Fielding "several complaints" from users that Mimi's presence was causing allergic reactions and that she had taken the occasional swipe at young children, it was decided Blueskin Bay Library's first cat would have to leave the area, she said.
"Some customers are pretty upset about losing her. I am particularly sad. I am going to miss her so much. She is a little burst of light wherever she goes."
Waitati residents are encouraged to say goodbye to Mimi before she moves to her new home.
