Rats, which serve as animal models, are dissected to obtain blood vessels for research. Pareidolia can make these lengthy experiments more interesting. The dissection of rats to obtain blood vessels is tedious, complicated, and bloody. Although careful, patient and well-practiced, discouragement and disappointment are inevitable. Short breaks can be taken during the procedure to reduce fatigue. During one such break, it was discovered that from a distance this sacrificed rat looks like a crazed cat.
