Studies
- PMID 42278121 (2026, Animals : an open access journal from MDPI) — Increasing Dietary Potassium Enhances Urine Production and Reduces Risk of Calcium Oxalate Stone Formation in Senior Cats.. The objective of these three studies was to determine if dietary potassium supplementation affects urine production or calcium oxalate (CaOx) relative supersaturation (RSS) in adult cats.
- PMID 41514733 (2025, Animals : an open access journal from MDPI) — Twenty-Four-Hour Feeding Patterns of In-Home Healthy Aging Cats Fed Wet, Dry, or a Combination of Wet and Dry Diets Ad Libitum.. Domesticated cats have evolved from the obligate carnivore <i>Felis silvestris</i>.
- PMID 41176630 (2026, Journal of animal physiology and animal nutrition) — Age-Dependent Increase in Small Intestinal Permeability and Sex-Dependent Absorptive Capacity in Cats (Felis catus).. Age-associated changes in intestinal permeability and function have not been studied in domestic cats, leaving a key factor in the relationship between age and digestive health in cats unexplored.
