“…The signaling pathways mediating these effects are thought to involve the peptide substance P acting on neurokinin 1 receptors, nerve growth factor, and possibly glucocorticoids, due to activation of the hypothalamic‐pituitary‐adrenocortical axis 10 . The testicular enlargement seen in the male marmoset can also be explained by a condition of stress, once a study on domestic cats revealed that acute stress increases testicular testosterone secretion 23 …”

Hyperadrenocorticism is a medical condition caused by the increase in cortisol production by the cortex of the adrenal gland. Although infrequently described in most animal species, its naturally occurring form, called Cushing's syndrome, is the most prevalent endocrinopathy in dogs. Cushing's syndrome is also present in humans and might be confused with the pseudo‐Cushing's syndrome (PCS), rarely described in animals. PCS shares many of the clinical and biochemical features of Cushing's syndrome. However, the hypercortisolemia seen is usually idiopathic and, in some circumstances, associated with psychological disruptions. This report describes PCS‐like disorder in two marmosets Callithrix aurita that were exposed to environmental changes, suggesting stress as the main cause of the process and reviewing the mechanisms involved in the pathogeny of the two syndromes.

“…Furthermore, a direct association has been established between cortisol and aggression in feral female cats [ 30 ]. A previous study has also shown that cortisol can increase testosterone secretion in vitro [ 31 ]. However, to date, no survey has explored the components of social behavior that may be related to GC concentrations in group-living cats.…”

Correlations between behavior and hormone concentrations or gut microbiome imply that domestic cats (Felis silvestris catus) living in a group are not like ‘groupmates’

Domestic cats (Felis silvestris catus) can live in high densities, although most feline species are solitary and exclusively territorial animals; it is possible that certain behavioral strategies enable this phenomenon. These behaviors are regulated by hormones and the gut microbiome, which, in turn, is influenced by domestication. Therefore, we investigated the relationships between the sociality, hormone concentrations, and gut microbiome of domestic cats by conducting three sets of experiments for each group of five cats and analyzing their behavior, hormone concentrations (cortisol, oxytocin, and testosterone), and their gut microbiomes. We observed that individuals with high cortisol and testosterone concentrations established less contact with others, and individuals with high oxytocin concentrations did not exhibit affiliative behaviors as much as expected. Additionally, the higher the frequency of contact among the individuals, the greater the similarity in gut microbiome; gut microbial composition was also related to behavioral patterns and cortisol secretion. Notably, individuals with low cortisol and testosterone concentrations were highly tolerant, making high-density living easy. Oxytocin usually functions in an affiliative manner within groups, but our results suggest that even if typically solitary and territorial animals live in high densities, their oxytocin functions are opposite to those of typically group-living animals.

“…), sejam elas comportamentais ou não. É importante ressaltar o quanto os gatos ainda são utilizados como modelos experimentais em inúmeros estudos científicos extremamente recentes, abordando assuntos como cardiomiopatias(VAN ESSEN et al, 2012) e envolvidos nas áreas de neuroanatomia(QUOC et al, 2012), psicologia (KONERDING et al, 2012 WELLS; MILLSOPP, 2012) , ecologia molecular(DEVILLARD et al, 2011), microbiologia(GERRIKAGOITIA et al, 2012) e fisiologia(GENARO;FRANCI, 2010;HOENIG et al, 2011). Assim, é um tanto surpreendente que relativa pouca atenção tenha sido voltada para o bem-estar desses animais, quando comparamos com a quantidade de material publicado para outros animais de criação(BRADSHAW; CASEY, 2005).…”
