'See you Monday!' Alana said as she left.
Danielle was in the monitoring room, she had signed up to cover the weekend at the Sanctuary. It was easy and paid more than her normal internship hours. It was a matter of delivering food to the various habitats and watching the cameras for problems. Most people spent the majority of their time reading or watching movies. Danielle always claimed that's what she was doing, but instead she worked down in the genetics lab.
None of the scientists would have imagined a 19 year old kid fresh out of high school would use their lab over the weekends. Danielle put a lot of thought into covering her tracks. This included lying about her GPA and not mentioning that she was due to attend MIT in the fall with a full ride. The internet was good for so much more than porn, and Danielle was well versed in cutting edge genetics and what was known of the inner workings of the newly appeared transformative diseases.
She was creating an improved version of the Gay Pride virus. She had seen the happiness and positive social structure the Pride had formed at her old school. Those transformed were physically, mentally, and emotionally superior to humanity. The problem was that they were all male and couldn't reproduce, they were an evolutionary dead end.
Danny was going to change that, and more. She started with the vial from Leon, and began experimenting using the labs extensive library of feline DNA.
Down in the lab, she recovered her samples from hiding. She had used cells from one of the Sanctuary's star attractions; Dalton, a melanistic cougar.
Checking them under the microscope, she was overjoyed to find them to be exactly as she left them. The cells were stable, which meant she could very well have what she needed.
She had hoped for this, and had a tranq gun loaded with this version of her formula. Ten minutes later she was in a Jeep cruising Dalton's enclosure.
She found him easy enough, Danielle knew all of his habits. As he sunned himself on rock, she put a dart right in his side.
The formula hit his system like a freight train; a cocktail of modified Gay Pride virus, metabolic accelerators, plus Smilodon, Liger, and even some of Danielle's own DNA.
The black furred cougar jumped to his paws. He made it barely a stride before stumbling. Danielle could see his fur rippling as his flesh transformed. Limbs stretched and his rib cage barreled. His upper canines pushed out past his lips, forming massive saber teeth. The cat went from Danielle's size to closer to that of a horse.
Dalton rolled back to his now enormous paws, and bolted into the woods. Danielle smiled, and watched the tracker display in the Jeep. The metabolic boost would burn off any moment, and drop him into complete exhaustion.
She followed in the Jeep, and two minutes later the signal stopped moving. She could see him sprawled on the trail in front of her.
Danielle approached cautiously. She could see his flanks slowly rising and falling. She inspected her handiwork.
Dalton was immense, well over half a ton she guessed. Eight inch sabers curled down from his upper jaw. His fur seemed thicker, but overall he seemed to be a massively scaled up sabertoothed version of his old self. Danielle walked around and lifted his tail. She smiled. 'His' might not be the best pronoun now. Tucked between the cat's sack and anus was a new female sex.
Danielle laughed to herself. 'This was a triumph, I'm making a note here 'huge success'". She sang in her joy.
She left the now hermaphroditic macro cougar, and backtracked. As expected she found a clawed up log basted in thick white fluid. She wasted no time and collected as many clean samples as she could. Gay Pride was only contagious for their first orgasm, so this was her single chance.
With the help of the mini crane and harness, she loaded up her test subject and drove back to the lab for examination.
