10.3 Hairball Vomiting: Systems to Backtrace
Feline Fat-Based Metabolism (Fat-Based Metabolism)
Index page: hairball vomiting → backtrace variables → upstream food structure → related mechanism chapters.
Hairball vomiting is an observable output. In Feline FBM it belongs to Observable Output Backtrace.
Not all hairball vomiting is ideal. Frequent hairball vomiting is not assumed as default healthy state. Hair should usually pass through stool when the pathway is stable.
Backtrace through Gastric Hair Residence Time, Hair Entanglement Probability, Gastric Emptying Speed, hair load, and clinical boundary.
Gastric Hair Residence Time before onward passage or regurgitation.
Hair Entanglement Probability when hair aggregates in stomach.
Gastric Emptying Speed under food structure.
Grooming volume and seasonal shedding.
Obstruction suspicion → emergency boundary.
hairball = always healthy
hairball = hairball paste only
hairball = motility disease by default
skip food structure when vomiting is frequent
Obstruction suspicion, blood in vomit, or protracted vomiting enter Clinical Boundary Layer.
This index lists systems and variables only. Not a clinical diagnosis system, not a treatment protocol, not an effect-guarantee system.
