The Griffin, the Tiger, and Their House Cat Omega by Lorelei M. Hart

All I wanted was someone I could shift with, could hunt with, could love. Fate sent me two.

Alpha griffin shifter Allen is used to hiding in the shadows. He’s not supposed to exist, and the rules of his pack are clear: Expose our kind and die. There’s one exception, one loophole—find his true mate. Only problem is there hasn’t been a true mate pairing among his kind in generations.
Alpha tiger shifter River packed up his life back east to raise his niece after a tragic accident left her an orphan. He’s starting his whole life over and doesn’t have time to have fun, much less date. But when he walks into Animals SD looking for a job, he scents his future. Now what?
Omega house cat shifter Matthew avoids shifters. House cat shifters are treated as less than and he’d rather live among humans and never be his true self than deal with that. When his boss asks him to do a sales call to Animals, the local shifter club, he’s stuck going to the place he fears. But what can he do? Tell his human boss he’s afraid of people who turn into animals being mean to him? That would go over well. He needs to suck it up for one visit. He can do this.
