Why Are Apricot Pits Harmful for Pets?

Apricot pits release hydrogen cyanide from amygdalin when crushed/chewed, rapidly halting cellular oxygen use and causing panting, bright red gums, dilated pupils, seizures, shock, rapid heartbeat, and respiratory failure. Flesh safe sparingly if pitted. Dogs, cats, birds, and reptiles succumb quickly without intervention. Emergency veterinary oxygen therapy, cyanide antidotes like hydroxocobalamin, and stabilization critical; pit removal essential.
