Shavin’s Mate by Clarissa Lake

Savin Kazza, a Narovian feline humanoid was an alien undercover on Earth when he was kidnapped by alien slavers thinking he was human. He was sold into slavery and sent to the mines on Breskaa where he thought his life would end.

Enter the Farseek Mercenaries, who are traveling through the Sargus Empire, searching for their stolen people who were kidnapped from Farseek and sold into slavery throughout the Empire. The mercenaries hate slavers and slavery, so while they are freeing their enslaved people, they free all the slaves on Breskaa. Savin readily agrees to go with them.

Nora Reed has also been kidnapped from Earth by Alien Slavers and now she is working for the mercenaries recording the refugees as they come aboard Dreadnaught One. Known for the irresistible pheromones felines give off when they find their soulmates, Nora is stunned when Sahvin’s innocent touch sets off an uncontrollable urge to mate with him.

From there things heat up.
