Gina Gershon was willing to do anything to get her loved one back.

And she means anything. When the actress lost her cat Cleo, she combed the streets of Los Angeles – and much more – to find the missing feline.

Gershon details her desperate measures in an “almost totally true” memoir, In Search of Cleo: How I Found My Pussy and Lost My Mind, out this month.

The book chronicles the How to Make It in America star’s bizarre and hilarious two-and-a-half month search for Cleo, who went missing when an assistant took him to a dog groomer.

Along the way, Gershon meets a pet psychic named Sonya Fitzpatrick who suggests that she leave a trail of her own urine from where she suspected Cleo might be lost, all the way back to her Los Angeles home.

“That was around three miles,” she tells PEOPLE. “That was a lot of pee.”
