Happy Mother’s Day to the women who: - kept tiny humans alive on 4 hours of sleep - ran entire households with cortisol levels that deserved a trophy - somehow always knew when you were lying - and passed down mitochondria with better work ethic than most CEOs Today’s assignment: Post a picture of your mom, your kids, or any other women that was "mom." Today, let’s fill this thread with the faces and stories that shaped us.

Your pet isn’t “expressing a mood.” They’re broadcasting metabolic data in real time. Most people think purring, panting, and tail flicks are “cute behaviors.” They’re not. They’re physiological readouts, the mammalian equivalent of a dashboard light, and your animal has been giving you a full report every single day without you realizing it. Today’s class is about teaching you to read the signals instead of guessing the story. PURRING: The Nervous System’s Morse Code Everyone thinks purring = happiness. But purring is a multi‑state regulatory mechanism, and the body uses it for far more than joy. What purring actually is: A vibrational frequency generated by the laryngeal muscles firing at 25–150 Hz, a range known to stimulate tissue repair, bone remodeling, vagal activation, and pain modulation. When cats purr, physiologically they may be: - Self‑medicating pain Purring increases endorphins and modulates nociception. If your cat purrs when injured, they’re not “being brave.” They’re activating an internal analgesic circuit. - Stabilizing their nervous system Cats use purring to downshift from sympathetic activation. Think of it as a built‑in vagus nerve stimulator. - Rebalancing respiratory mechanics The oscillation helps maintain airway patency and oxygenation during stress. - Repairing microdamage Those frequencies stimulate bone density and soft‑tissue healing. (Yes, your cat literally vibrates themselves back to health.) The red flag version: If your cat purrs while withdrawn, hiding, or refusing food, that’s not contentment. That’s compensation. PANTING: The Metabolic Pressure Valve Panting is not “they’re hot” or “they’re excited.” Panting is a thermoregulatory, respiratory, and acid‑base balancing maneuver that kicks in when the body needs to offload heat, CO2, or stress metabolites. Panting tells you about: - Heat load - Dogs don’t sweat like humans. Panting is their evaporative cooling system. - Cortisol spikes - Stress increases metabolic heat and CO2 production. Panting is the off‑ramp. - Blood pH shifts - Rapid breathing reduces CO2 to correct acidosis. (Yes, your dog is doing chemistry with their lungs.) - Cardiac strain - Panting at rest can indicate heart workload, poor oxygenation, or circulatory compensation. - Pain - Pain increases sympathetic tone = increases metabolic demand = triggers panting.

"My cat drools big time when he’s on my lap. What does that mean?” Short version: Drooling is a parasympathetic overflow. Your cat’s nervous system is sliding so far into “rest‑repair‑digest” mode that the salivary glands turn on hard. But here’s the part most people don’t know: Drooling can mean two completely different physiological states, one healthy, one compensatory. Let’s decode both. 1. The Healthy Version: Deep Parasympathetic Drop Some cats drool when they’re: - extremely relaxed - deeply bonded - kneading - in a trance‑like comfort state - activating old kitten nursing pathways This is the “I feel safe enough to shut the world off” physiology. It’s the same reflex kittens have when nursing, salivation + kneading + purring. In adults, it shows up during deep relaxation with a trusted human. If the cat is: - loose in the body - slow blinking - purring softly - breathing steady - not hiding or withdrawing afterward this is a good drool. 2. The Red Flag Version: Compensation, Not Comfort Drooling can also be a stress‑relief maneuver when the body is trying to downshift from: - nausea - dental pain - GI discomfort - anxiety - motion sickness - sympathetic overload Here’s the physiology: When the vagus nerve is activated to counter stress or nausea, salivation increases. So drooling can be the body’s way of buffering discomfort. Red flags include: - drooling + tension - drooling + panting - drooling + hiding - drooling + swallowing repeatedly - drooling only in certain positions - drooling that starts suddenly in adulthood - drooling paired with bad breath or pawing at the mouth This is not comfort. This is compensation. How to tell which one it is Ask these three questions: 1. What does the body look like? Loose = parasympathetic Tense = compensation 2. What happens after the drooling? Returns to normal = safe. Withdraws, hides, or acts “off” = discomfort 3. Is it new or lifelong? Lifelong = normal pattern. New = investigate

Another one of my horses. This is only his 2nd race. He just turned 3 in March! Watch what this boy does. He is #3. Kept me on the edge of my seat. https://www.facebook.com/reel/4330383997227974
