The inscentive for pet Alyssa to be quiet is that she'll be disposed of if discovered, and she doesn't want to.
Naturally, one of the perks of having Alyssa as a pet is ability to hide her in plain sight, sorta- if Alex is caught with the small Alyssa, they can both pretend she's the big Alyssa and they're just playing around again, the only problem is with discovering two Alyssas at once, so they two try to stay away from each other. This makes Alex spend a lot more time with small Alyssa, with all the consequences stemming from their relationship.
