An international research collaboration reports that domestic cats age in ways that resemble human aging, with comparable patterns of age-related brain deterioration. The work, conducted by scientists at the University of Bath in the U.K., Auburn University College of Veterinary Medicine in the U.S., and École Nationale Vétérinaire de Toulouse in France, finds similarities in brain changes that track with age. The researchers describe evidence of brain shrinkage and other structural or functional alterations that progress in a manner broadly consistent with known human age effects.
Because cats show these parallel biological and neurological aging features, the study suggests they could serve as useful models for investigating the mechanisms of healthy aging and age-associated neurological conditions. The findings also point to the possibility that insights gained from studying cats could inform research relevant to human brain health, while supporting comparative approaches that connect veterinary and human medicine. The study presents the underlying biological similarity as the key rationale for exploring cats further in aging and neurological disease research.
