While the dog may view the interaction as play or nervous release, the cat experiences it as an invasive physical threat. A domestic cat weighs between 8 and 12 pounds on average. A medium-to-large dog can easily weigh four to ten times that amount. The physical disparity makes mounting dangerous for the feline's spine, ribs, and hips.
Cat owners must recognize early feline stress signals before defensive violence erupts. Cats rarely jump straight to scratching; they display clear escalating warnings:
A stressed cat flattens its ears back against its skull in an "airplane" posture. Its tail base twitches or lashes violently side to side. The pupils dilate, and the skin along the back ripples. If the dog ignores these cues and mounts, the cat freezes initially before unleashing guttural growls, sharp hisses, and defensive claw strikes.
This dynamic creates acute medical risks for both animals. A cornered cat striking defensively can cause corneal scratches or severe ocular trauma to the dog. Conversely, a frustrated dog can slide from awkward mounting into predatory drift, mistaking the squirming, vocalizing cat for prey. What began as awkward humping can turn into severe physical injury within seconds.
