Subject: Rattus norvegicus domestica, 450 g

PE012 priming: Yes

Compound: PE027

Objective: Establish PE027's phenotypic range for subject species, evaluate cost/benefit of subjects trained for voluntary self-dosage

Protocol: Enclosure with a water pool, voluntary dosage from food dispenser

Live observation: Trained subject, first dosage after 5 minutes.
After an initial calm period subject rubs off their fur on the enclosure's wall, revealing metallic scales.
Three dosages in short succession, after which subject falls over.
Subject is placed in the water by robotic arm, where it began swimming.

Dissection findings: phenotypic changes consistent with PE027's usual profile - in this case the gills replaced the upper lobes of the subject's lungs, opening to the outside over the scapula.
Digestive track shortened considerably, liver atrophic, teeth replaced by needles reminiscent of an anglerfish.
Blue fluorescent organ between the hemispheres.
