I suggest that catpeople can be egible to suffer from taurine deficiencies, which causes them to become weak over time (low stamina, wont crash out) as well as induce blindness & loss of appetite/vomiting within them until they eat taurine, which isn't a chemical, but eating from carnivorous raw meat foodgroups helps avert it. A temporary buff to make only love raw meat while they are currently suffering from the deficiency would also stop them vomiting later.
