It’s Thursday September 3, 2026, and here’s your Thursday tour of animals that do not smell good in your garage during a 90+ degree heat wave.
Let’s talk about animals in cages - and the decompensation that can occur anytime during/following capture and confinement. Let’s face it - you find a hurt or injured animal, and you think you’re doing the right thing by helping it. So you assume the animal also knows it’s being helped, because you love animals, and they always find you when they need help, etc. “It’s so calm! It loves when i talk to it and pet it and sing to it! It knows I’m helping it, right?!” Wrong.
If you’ve ever called me about a bird, deer, or bunny, you’ve likely heard me talk about capture myopathy. What is capture myopathy? It’s an often-fatal deterioration and chain of events caused by capture, transport, fear, restraint, etc. Does this mean the animal died of fright? No, it’s more complicated than that. It’s a combination of severe stress and muscle breakdown from exertion. The science behind it is this - during capture, the nervous system (specifically the sympathetic ) floods the body was fast-acting stress hormones like adrenaline. As the animal preps for escape, its HR, BP, breathing and muscle activity all rise quickly. Over time, muscles consume oxygen and energy faster than it can be replenished, and here’s where things really snowball. Muscles now have to rely on anaerobic metabolism, contributing to acidosis. The breakdown of damaged muscles is called rhabdomyolysis, a process that will release stuff like myoglobin and potassium into the bloodstream - myoglobin is now going to damage the kidneys, and potassium and electrolyte imbalances are going to damage the heart. And now you can see why it’s more than simply dying of fear - it’s a snowball effect that truly throws off the balance in the whole body. Pursuit, capture, restraint, transport, and struggling can all lead to capture myopathy - which is why it’s not unusual for animals to die soon after entering rehab. Are certain animals more prone to this response? Yes. Deer, birds, and bunnies are quite prone to capture myopathy. Also, it’s worth mentioning that stillness is not compliance or trust. Deer, rabbits, and many birds will freeze when terrified. So while you’re petting it, singing to it, or talking to it, and the animal is so quiet and still - you likely are further stressing an animal in crisis.
