Kissed By Cat by Shirley Jump

By day a woman…by night a cat… and only by being loved as both will the spell be broken…

Catherine Wyndam has spent two hundred years under the curse of a vindictive witch. Now, in her last week before the spell is permanent, she wants nothing more than to experience the kind of life she always wanted: a white picket fence, a cozy home, and a few creature comforts. Her plans are thwarted, however, when veterinarian Garrett McAllister plucks her off the nighttime streets and takes her to his animal shelter.
Garrett McAllister is much better with animals than humans, and his vet practice and fledgling shelter mean everything to him. Until the cat he rescues disappears, seemingly replaced by a beautiful woman with an uncanny knack for calming his furry clients. He hires her as an assistant, but before long it’s clear that their connection is deep and true. She’s the woman he’s always been waiting for.
But Catherine watches the hours tick by and knows her time is limited. Can she possibly tell Garrett the truth in time to break the spell?
