 SCP-597 is a blob of flesh where the substances expand and ripple. All over its body, mostly located on its rolls, are hundreds and hundreds of teats of various colors and sizes. Whenever a mammal is released into its cell, it will be drawn to the corresponding teat for its species and then proceed to suckle as long as they are unimpeded. The milk released will be identical in every way to the makeup of the subject's mothers, although able to sustain the subject's nutritional needs indefinitely. While the fluid is the same as normal milk, chemically, for some reason, whether it be an effect of the SCP or an unknown quality of the substances it excretes, any full-grown mammal that would normally require more can survive to the end of their normal lifespan, give or take a few years, simply by suckling at the nipple. Although their teeth will fall out.
