I really enjoy this series, all revolving in some way or another around cats. The "sleuth" is an actress who is semi successful, but who needs a day job to stay afloat financially, so she "cat sits" for various cat loving owners who much leave their pampered kitties. It's her "day job" that brings the murders to her attention. Her love life sometimes intrudes (a bit PG 13, but not explicit) with its casual attitude towards extra marital sex, but the stories are charmingly told with eccentric and real feeling characters and cares.
What do You think about A Cat In Wolf's Clothing (1991)?
