WHAT NOT TO DO: Avoid forcing intense exercise to “build mitochondria,” especially in a cat that is already reluctant to move. Avoid fasting or skipping meals to chase autophagy, because cats are not built for that strategy. Avoid adding multiple supplements at once, which can upset the stomach and blur cause-and-effect. Finally, avoid assuming a slowdown is purely “aging” without checking for treatable problems like arthritis, dental pain, anemia, or kidney disease.
Instead, make the environment do the work. Add steps to favorite perches, raise food and water slightly for cats with neck or back stiffness, and place litter boxes on each level of the home. Choose play that encourages natural stalking rather than jumping—slow wand movements, rolling toys, or short hallway tosses. These changes reduce strain while still giving the body a reason to maintain cellular housekeeping. If a cat’s comfort improves, activity often returns in small, meaningful ways.
