You reach the room and walk inside, following behind the lady. She tells you to get onto the table, so you hop up, landing rather gracefully on all fours. She goes on to explain what is going to happen now.
"Alright, these next few rounds will be tougher on you physically. But bare in mind that this isn't nearly as bad as if we had to do it surgically. This one should take about 20 minutes to fully complete however, so be prepared."
She injects you right away, sticking nearly 30 syringes into your body. You can feel so many different areas of yourself start to itch and tingle as your leg bones resize and leg muscles strengthen. A similar thing happens to your arms, leaving you with just slightly longer legs than arms. Enough to have your ass still stick up just a bit while you are down on all fours. It also allows for your breasts to hang more evenly spaced, as your body is no longer under such a significant backwards arch.
You are instructed to stand up, and do so. You note that you seem to be a few inches shorter, but overall do not feel all that different. The lady gives your body a quick examination and confirms that everything has worked out well enough as your neck finishes lengthening the last inch of growth. It still looks relatively normal, just with maybe 2 inches more of neck then before, while you are standing on 2 legs at least. You test out how it looks on all fours, and the change is larger than you expected. You now can be nearly standing up and are all most able to kiss the ground still. You also can more easily look behind you. And after being told to try it, you also discover that you can in fact, kiss your own pussy with your lips.
"There, that takes care of your body's physical shape. Now for the organs and glands" Says the lady as she grabs a single syringe and sticks it up your nose. She also grabs several more from a different tray and pokes them into various spots on your body.
After a few moments pass, you suddenly can smell so much better, and your ability to focus on certain scents, sounds, and movements has drastically been improved. You also become acutely aware of your own oder. It is not necessarily a bad or good smell, but you can easily identify it, which is the important part.
"That takes care of enhancing your sensory inputs and adding your scent glands. Only 2 more rounds to go. This next one is going to correct your digestive system, so once this is done, you should try to keep in mind that panthers are primarily carnivores. This means that you should be limiting your non-meat based foods from now on. Though perhaps a special cat food would be alright as well? The maybe good news is that you will be able to eat raw meats now with no issues to your health."
"Is that really considered to be a good point?" You ask questioningly. The lady shrugs, "up to you at this point." She then gives you an additional injection into your stomach, and 2 into your intestines.
It is a good thing you didn't eat for a while, as if you had, you would definitely throw it up right now. Your stomach is cramping and your entire torso just feels uncomfortable overall. Thankfully this only lasts for about a minute. But you do still end up dry heaving a few times.
You spend a few minutes recovering from that ordeal and are reminded that this is the last round of injections before the final stage, your claws. 20 quick injections, one in every single finger and toe. Each one bringing about a brand new retractable claw for you. It is kind of neat how you can push them out and pull them in at will. Though they do also look kind of weird when pulled in.
"And that about does it. You are all done with injections. Your new employeer should be waiting for you in our VIP lobby as well. But, before you go, I have a present for you." Says the lady. She tells you to not look, so you close your eyes. You then feel something get wrapped around your neck. She tells you that you can look now, and you find that a black choker with some lacy white frills has been placed around your neck like a collar. It even has a metal loop in the back to attach a leash to, and also has a metal plate for engraving your info on in the front. You thank her for the gift, then follow her out as she leads you to the VIP lobby to hand you over to your new employeer/owner.
