Preheat the oven to 350 degrees Fahrenheit and prepare a 9" springform pan with parchment paper. Place a sheet of parchment paper on the springform base, then close the springform "ring" onto the base, tightly trapping the parchment paper.
In a large bowl, stir together the animal cracker crumbs, salt, and almond milk. It should look like a dough. Press the mixture into the prepared pan and set aside.
In a stand mixer bowl fitted with a whisk attachment, add the yogurt and cream cheese. Mix on medium speed until completely smooth.
Reduce the speed to low and add one egg at a time. When completely smooth, add the stevia and key lime zest.
Bake the crust you set aside earlier in the oven for 14 minutes. While that bakes, finish off the filling.
Finally, add the key lime juice to the mixer to whisk until the crust is done baking.
Take the crust out of the oven, then pour in the cheesecake filling. Bake for 1 hour and 15-20 minutes. Let cool at room temperature, then cover and refrigerate overnight. The next day, slice, serve, and enjoy!
