Study of tree shrew biology and models: A booming and prosperous field for biomedical research

The tree shrew ( Tupaia belangeri) has long been proposed as a suitable alternative to non-human primates (NHPs) in biomedical and laboratory research due to its close evolutionary relationship with primates. In recent years, significant advances have facilitated tree shrew...

The promotion of play behaviour in grow-finish pigs: The relationship between behaviours indicating positive experience and physiological measures

The provision of opportunities to express rewarding behaviours is a promising concept to support a better quality of life for intensively farmed pigs. Play behaviour has been associated with excitement and fun, suggesting that playing animals experience pleasurable states. Pigs...

Teeth baring as a model to understand complex facial signals in a tolerant macaque species

Facial communication regulates many aspects of social life in human and nonhuman primates. Empirically identifying distinct facial expressions and their underlying functions can help illuminate the evolution of species' communicative complexity. We focused on bared-teeth faces (BTFs), a highly versatile...

Chimpanzee activity and behavioral diversity extends across 24 hours in both captive and wild settings

Studying nocturnal behavior is crucial for understanding the full scope of a species' behavioral flexibility so as to inform the conservation of wild populations and the care of captive individuals. However, this aspect of primate behavior is understudied, especially in...

Are you serious? Relaxed open mouth may unveil the competitive/cooperative nature of play fighting in two feline species

Play fighting is a multifunctional behaviour allowing the development of both cooperative and competitive skills. During play fighting, animals perform ‘competitive' actions that are typical of the agonistic context and/or ‘cooperative' actions to avoid escalation into aggression. Several structural features...

Social sham chewing in sows?

In this short communication, we describe chewing behaviour in sows with no apparent edible substrate in their mouth as a potential social behaviour. Chewing in sows during interaction with unfamiliar sows was unexpectedly observed in a study assessing social abilities...

Disentangling developmental effects of play aspects in rat rough-and-tumble play

Animal play encompasses a variety of aspects, with kinematic and social aspects being particularly prevalent in mammalian play behaviour. While the developmental effects of play have been increasingly documented in recent decades, understanding the specific contributions of different play aspects...

Cats just want to have fun: Associations between play and welfare in domestic cats

Play is often considered an indicator and promotor of animal welfare and may facilitate closer cat-human relationships. However, few studies have empirically investigated these associations. The current study aimed to investigate play-related factors associated with four welfare outcome measures in...

Feline faces: Unraveling the social function of domestic cat facial signals

Lately, there has been a growing interest in studying domestic cat facial signals, but most of this research has centered on signals produced during human-cat interactions or pain. The available research on intraspecific facial signaling with domesticated cats has largely...

Rescued cats prefer to scratch fabrics commonly used to cover upholstered furniture

Preference responses of cats for scratching fabrics commonly used on furniture were evaluated during four consecutive days in three Non-Governmental Organizations (NGOs) that rescue companion animals. Cats were grouped and their choices were registered at a group level (no individual...
