With increasing numbers of aged cats, veterinarians face a growing incidence of dysrexia situations that markedly worsen prognosis, especially in the presence of comorbidities such as chronic kidney disease. Feeding difficulties in older cats rarely originate from the composition of the diet alone. Instead, they arise from a multifactorial interplay of sensory decline, chronic pain, cognitive decline, mobility impairment, and environmental or social stressors that disrupt the expression of normal feeding behaviour.Cats are carnivores with distinct feeding behaviour characteristics that must be understood in order to provide appropriate nutritional recommendations, extending beyond the simple selection of a diet that meets nutrient requirements. Feeding strategies must take into account food distribution (spatial and temporal organisation of food presentation), the surrounding environment, and the species' natural activity patterns. Ageing further increases the need to adapt the behavioural component of nutritional management. Ageing affects olfaction, gustation, vision, hearing, circadian feeding rhythms, motor abilities, and socio-cognitive function, all of which influence a cat's capacity to locate, access, evaluate, and consume food. Chronic pain may also reduce meal frequency and size. Cognitive dysfunction may impair spatial navigation, disrupt foraging sequences, or alter appetite, while systemic inflammation may exacerbate muscle loss and reduce behavioural engagement.Beyond diet formulation, clinicians must consider the ways ageing cats interact with their environment and caregivers. Integrating ethology, sensory biology, pain assessment, and environmental management with nutritional strategies is critical to quality of life in older feline patients. This review calls for greater recognition of these intertwined mechanisms and urges clinicians to move \"beyond the bowl\" when supporting ageing cats.</p>","PeriodicalId":15851,"journal":{"name":"Journal of Feline Medicine and Surgery","volume":" ","pages":"1098612X261487063"},"PeriodicalIF":2.6,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148969389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence-Based Nutrition for Ageing Domestic Cats.","authors":"Emma Bermingham, Sara Hoummady, Tanya Schoeman, Marjorie Chandler, Nathalie Jane Dowgray","doi":"10.1177/1098612X261491120","DOIUrl":"https://doi.org/10.1177/1098612X261491120","url":null,"abstract":"<p><p>With the increasing life expectancy of domestic cats, there is a growing imperative to understand and address the unique nutritional needs of senior felines. This review critically examines current knowledge regarding the physiological changes associated with feline ageing, the nutritional requirements of older cats, and the gaps in research and regulatory nutritional standards that persist in this field. Despite the importance of nutrition, there are no official guidelines for senior or geriatric cats. Veterinary recommendations focus on energy, protein, fat (including essential fatty acids), and water, but these are largely extrapolated from adult cat requirements. The literature reveals a focus on canine ageing, with feline-specific studies remaining scarce. Where research exists, it highlights the benefits of enriched diets (e.g., fish oil, vitamins, B vitamins, arginine) and targeted supplementation (e.g., vitamin E, ß-carotene, linoleic acid, chicory root) in improving cognitive function, longevity, and intestinal health. However, robust, contemporary evidence for nutritional interventions in ageing cats is limited. Energy requirements, which underpin diet formulation, are inconsistent between studies and largely rely on non-peer reviewed data (i.e., conference proceedings) or meta-analyses. Protein is central to feline health, yet optimal levels for seniors are not empirically established, and age-related amino acid requirements are largely unexplored. Fat digestibility may decline with age, but the impact on fat-soluble nutrient status (e.g., vitamins A, D, E, K) is not well understood. Micronutrient deficiencies, particularly in B vitamins (B6, thiamine, B12), are more prevalent in older cats, often due to reduced intake and assimilation. Regulatory frameworks lack senior-specific nutritional standards, and commercial diets marketed for older cats often do not differ substantially from adult formulations. This review calls for evidence-led approaches, advocating for reputable brands that conduct dietary trials and publish peer-reviewed data on their senior formulations.</p>","PeriodicalId":15851,"journal":{"name":"Journal of Feline Medicine and Surgery","volume":" ","pages":"1098612X261491120"},"PeriodicalIF":2.6,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148956011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The owner's personality was assessed using the French version of the Big Five Inventory. Two outcomes were defined: (1) use of a non-conventional diet (yes: n = 439) and (2) inclusion of fresh meat-based foods in the diet (ie, not exclusively commercial with fresh meat; yes: n = 61). Two multivariable logistic regression models were built, with owner personality traits as explanatory variables.

Hypoglycemia was induced using a constant rate infusion (CRI) of rapid-acting insulin lispro. Glucagon nasal powder (single-dose, ready-to-use) was given intranasally and rectally and compared with SC glucagon injection and IN sham control. Blood glucose (BG) concentration was measured from samples collected at baseline (T-15), after induction of hypoglycemia (T0) and at 5-min intervals for 30 mins, and then at 15-min intervals for 1 h after glucagon administration. Plasma glucagon and potassium (K⁺) concentrations were measured at T-15, T0, T15 and T30 after glucagon administration. The time taken to prepare and administer each treatment was recorded.ResultsMedian BG was 2.6 mmol/l at T0 and increased significantly after glucagon administration by all routes, reaching peak median concentrations of 11.2 mmol/l (IN), 9.7 mmol/l (RCT) and 10.15 mmol/l (SC). Plasma glucagon concentrations increased markedly by T15, with the highest concentrations observed after IN administration (1562 pmol/l), followed by SC (191.7 pmol/l) and RCT (158.5 pmol/l) routes of administration.

Regardless of the reason for presentation, the owners of all cats presented to the cat clinic during that time period were systematically interviewed regarding chronic gastrointestinal signs. Cats with suspected chronic gastrointestinal disease underwent non-invasive diagnostic evaluation, and those with persistent suspicion proceeded to gastrointestinal biopsies. Full-thickness gastric and small intestinal biopsies were collected from each cat to evaluate histopathological lesions and to determine the presence and localization of Helicobacter species in the stomach. A total of 154 cats that underwent biopsies were included in the study. A subset of Helicobacter-positive samples was further analyzed to the species level using the nanopore sequencing technique.ResultsAll cats had chronic small intestinal disease.
