Strange Pet Habits Explained: The Science Behind Your Pet's Weird Behavior

For most dogs, eating grass occasionally is completely harmless and considered normal behavior. Theories include digestive aid, boredom, nutrient seeking, or simply enjoyment. The concern is if your dog suddenly eats grass excessively — which can sometimes indicate GI discomfort — or if the grass has been treated with pesticides. Vomiting after grass eating is common but not universal.

Research and behavioral observation point to several reasons: cats bat at objects to test whether they're alive (a prey-hunting behavior), to get your attention (because it reliably works), and because it provides sensory feedback. It's also a form of environmental exploration. If it becomes disruptive, redirect the behavior with interactive toys that satisfy the same instinct.

Zoomies (formally called FRAPs — Frenetic Random Activity Periods) are sudden bursts of energy often triggered by: pent-up energy after a long rest, after using the bathroom (particularly in dogs), after a bath, or in the evening as natural activity cycles peak. They're completely normal and a healthy release of energy. If they happen very frequently, it may signal insufficient exercise.

The most likely explanation is scent masking — an ancient predatory strategy to disguise their own scent while hunting. Another theory is scent marking: bringing an interesting smell back to the pack. While it's deeply unpleasant to us, it's instinctively satisfying to dogs. Managing it is mostly about supervision and recall training.
