A study published in Applied Animal Behavior Science has upended the common interpretation of cats licking one another as a purely affiliative act. Researchers at Ghent University in Belgium analysed video submissions from 53 multi-cat households across Europe, observing 106 animals. They found that while much allogrooming focused on the head and neck—areas difficult for a cat to reach alone—roughly 20 per cent of these interactions triggered ear rotation, head-shaking, or even biting in the recipient, signals consistent with irritation or fear. The behaviour, the authors note, appears to function in at least two distinct contexts: social bonding and social tension.

Viewed from the research team in Flanders, the findings suggest a more nuanced feline social repertoire than previously documented. In a subset of interactions, a cat would stand over a seated companion and lick it persistently, often prompting the groomed animal to vacate a favoured resting spot. Lead author Morgane Van Belle described this as an elegant conflict-resolution strategy: rather than resorting to overt aggression, a cat may use unwanted licking to displace a rival without risking injury. The study, while limited to a relatively small sample, is among the first to systematically code body-language markers alongside allogrooming, moving beyond owner questionnaires that have dominated the field.

Parallel insights from canine behaviour specialists reinforce the broader theme that pet owners frequently misread non-verbal cues. In Italy, trainer Max, who shares educational content with over 170,000 followers, has highlighted a specific tongue-curling signal in panting dogs that indicates the transition from normal cooling to medical emergency. In Brazil, behaviourist André Cavalieri emphasises that a dog’s anxiety or disobedience often mirrors the owner’s emotional state, as canines read posture, energy, and routine more than verbal commands. Argentine psychologist Stanley Coren similarly notes that a dog’s choice to sleep pressed against its owner reflects a search for security and group belonging, not mere comfort.

These findings converge on a single practical implication: the need for owners to become more literate in species-specific body language. The Ghent study’s authors caution that chronic, low-level tension in multi-cat homes can go unnoticed, potentially affecting welfare. The next milestone for feline social research will be longitudinal studies tracking how these subtle agonistic behaviours correlate with stress biomarkers over time. For now, the evidence suggests that a lick is not always just a lick.
