Riassunto

Durante il comportamento di lotta del gatto libero non anestetizzato si osserva tachicardia e aumento della gettata cardiaca; la pressione arteriosa e la conduttanza periferica totale variano relativamente poco. Si ha una marcata vasocostrizione mesenterica, mentre il letto iliaco subisce modificazioni di senso opposto a seconda dell'attività motoria dell'arto posteriore. In assenza di movimento si ha una vasocostrizione, che interessa non solo il letto cutaneo ma anche quello muscolare; questa vasocostrizione viene invece soffocata da una cospicua vasodilatazione, d'evidente origine metabolica, ogni qual volta vi sia attività muscolare locale.
