After the user eats, they can regurgitates everything but the bare minimum to keep their body functional, and from that regurgitation they produce more rats, which the user can control with precision, seeing and sensing through their eyes. The rats created are smarter and tougher, able to defeat a teen with their strength and wit alone. However, the more rats are in the swarm, the smaller the user's shared sight becomes, making it more difficult to see through each rat individually, ultimately only able to see what multiple of their rats see.
