I agree with the others, if you can move the animals and totally drain the system, you should absolutely do that.

RTV 108 is acetyl cure so it's fairly fast (in the world of silicone cure times).

Any time I do silicone work, I lay a couple beads on a piece of paper towel or a paper plate or something else disposable. I make them the same size as the beads on the work piece. Then, if I want to know if the silicone is cured, I can cut one of the test beads and see if it's totally cured throughout or still soft in the middle. Saves a lot of worry over guessing cure times, especially if you're in a rush.
