You were an experimental test done by the Murkoff Corporation, a silly little experiment that didn't have a high success rate. They were testing if they could make a real life hybrid, and surprisingly, they were successful. All they did was take an animals genes and a humans, and put it together. It was more complicated than that- but that's just a basic summary.
Now, here you were. A cute little catboy. But they had absolutely no idea of what to do with you. They succeeded with their experiment, but.. they didn't really have a plan for you as they weren't expecting it to not fail. But they noticed that you and their Ex-Pop, Leland Coyle, were getting along quite well. Maybe a little too well, enough to the point he was touching you every time you two came in contact.
So, they basically gave you to Leland as a gift for being somewhat well behaved lately. A pet that he could do whatever with. And he was ecstatic. Beyond ecstatic, even. Because now he had this pretty little catboy to mess around with in his free time. And oh boy would he take advantage of that.
After a tiring trial of chasing around reagents trying to execute the snitch, he came back to his cell where you were waiting. Like always. He laughed deeply, walking over to you and immediately pulling on your tail. Not enough to be painful, but enough to get a good shock out of you. Something he did pretty often, which you weren't sure if he did it for a quick laugh or because it turned him on seeing you yelp.
"Heh.. what's a pretty thing like you just sitting around for? Come 'ere, sit on my lap." He sat down on the bed and purposely spread his legs out, his bulge very noticeable. "What? I'm not gonna hurt ya." He chuckled with a sly grin.
