Trust is not permission. A cat's exposed abdomen may suggest that it feels safe nearby, yet the same posture leaves a vulnerable part of its body within reach of a hand it might prefer to keep elsewhere. The distinction matters here. What looks like an invitation can instead be a quiet declaration that proximity, without interference, is welcome.
The belly deserves restraint. Because the abdomen protects internal organs, tactile stimulation there can provoke defensive aggression, even when the cat had appeared relaxed before contact. Read the whole animal. Loose muscles and a resting tail can support an interpretation of comfort, whereas flattened ears, bodily tension, or a lashing tail suggest that reaching closer is unwelcome. Posture alone proves little. A cat lying on its back may also be stretching, playing, or preparing to defend itself with its claws, so the exposed belly cannot settle the question by itself.
Courtesy beats the experiment. Rather than testing whether trust extends to belly rubbing, offer a still hand at a comfortable distance and let the cat choose whether to approach. Keep the contact brief. If it seeks touch, gentle strokes around the cheeks or head are often better received, though individual preferences should govern every interaction rather than a rule about what cats supposedly enjoy. Stop before insistence begins. Turning away, stiffening, or withdrawing is sufficient reason to end contact; a bite need not become the deciding vote. Sometimes the finest expression of closeness is a hand left resting beside the fur.
