Recent research sheds new light on the motives behind feline grooming behaviour. Contrary to longstanding beliefs that cats groom each other primarily as a sign of affection, a new study suggests that licking may sometimes serve a more antagonistic purpose.

The study, published in the journal Applied Animal Behaviour Science, was led by Morgane Van Belle, a behavioural scientist at Ghent University in Belgium. Van Belle’s inspiration stemmed from observing her own cats, Fabio and Giovanni, in their frequent tussles over coveted napping spots. Notably, she noticed that one cat would lick the other in an apparent attempt to displace them, demonstrating a less friendly side of mutual grooming.

Typically, allogrooming, or mutual grooming, has been characterised as a cooperative behaviour, where animals help each other with hard-to-reach areas such as their necks or backs. However, Van Belle’s observations challenged this notion. “Allogrooming is commonly described as a friendly behaviour. However, in my own cats, I saw it was sometimes not so friendly,” she remarked during an interview.
The typical scene of Fabio basking in sunlight and being licked by Giovanni would often escalate into biting, forcing Fabio to vacate the sunny spot and allowing Giovanni to take over. This intriguing dynamic led Van Belle to ponder whether similar behaviours could be witnessed in other households with multiple cats.
To explore this hypothesis further, Van Belle and her team gathered footage from 53 households across Europe, each containing two or more cats. The recorded interactions revealed a surprising range of behaviours, highlighting that not all grooming is motivated by kindness. In particular, some cats were found to engage in grooming that resembled bullying.
The results varied significantly across the collected videos. In some clips, cats displayed typical allogrooming behaviours, such as licking each other’s heads and necks while enjoying a peaceful cuddle. However, other footage showcased a more complex interaction. Here, grooming often preceded conflict, as the grooming cat exhibited aggressive behaviours whilst the recipient displayed signs of stress.
Common stress indicators in the licked cat included staring, vocalisations, and lip-licking, suggesting that what was meant to be an act of care might instead have incited discomfort. “Licking may sometimes be a way for cats to express their displeasure without escalating into full-blown fights,” Van Belle explained.
Interestingly, the study indicates that cats possess a certain level of social intelligence, opting for subtlety in conflict resolution rather than outright aggression. “They could walk over and swat another cat in the face to get the blanket it is lying on. Instead, they lick it a little and fuss around. They have these very subtle ways of resolving conflict,” Van Belle noted.
These findings open the door for further research, prompting a broader investigation into the complex social relationships of cats. Van Belle stated her intention to expand the study to encompass more aspects of cat interactions, seeking to identify the nuances of relationships formed amongst them.
Understanding the dynamics of cat behaviour could prove beneficial for pet owners, allowing them to better interpret their pets’ actions and improve their social environments. With continued exploration into these relationships, researchers hope to unveil the intricacies of feline communication, revealing how cats navigate their social worlds.
As pet ownership increases, insights gained from this study could not only enhance the well-being of cats but also strengthen the bond between humans and their feline companions. A deeper comprehension of these behaviours could lead to a more harmonious coexistence within multi-pet households, firmly establishing that understanding cat communication is as crucial as loving them.
