Alien Alliances by Clarissa Lake

The United Alliance of Worlds has been protecting and visiting Earth for centuries. Star ship Raptor One carries a crew of humans and feline humanoids. The Narovian felines can and have interbred with humans during all that time. Many felines have found their true mates among the Earthers. Immediately on recognition, the felines give off pheromones that cause their true mates to desire them sexually so intensely that they must mate almost immediately.

Once Narovians started finding their meomee or true mates there a savvy businessman found away to profit from it. The Narovian Genetic Matchmaking Agency has set up shop on Earth, under the guise of genetic testing for ancestral origins and genetic markers for disease. This brings a new set of challenges to the crew of Raptor One under feline Captain Dargan Merrek as they protect Earth from alien hostiles amid sexy encounters with true mates.
