At what age is a Siamese cat considered senior?

Cats are generally classified as senior from around 11 years. Given that Siamese cats often live 15–20 years, it is worth beginning senior-oriented veterinary monitoring (twice-yearly check-ups, kidney function screening) from around 10–11 years, even when the cat appears healthy.

Should I switch my senior Siamese to a senior cat food?

Senior-formulated cat foods can be appropriate, particularly those emphasizing highly digestible protein, increased moisture, and lower phosphorus. However, do not switch to a low-protein diet without veterinary guidance — protein restriction is only appropriate for cats with advanced kidney disease. Your vet can recommend the best diet based on your individual cat's bloodwork and health status.

My older Siamese is losing weight — should I just feed more?

Unexplained weight loss in a senior cat is a signal that warrants a vet visit, not just increased food quantity. Common causes include hyperthyroidism, kidney disease, diabetes, and dental pain — all of which are treatable or manageable, but need a diagnosis first. Simply increasing food without addressing the underlying cause is unlikely to be effective.

How do I keep my senior Siamese mentally stimulated?

Siamese cats remain highly social and interactive even in senior years. Short play sessions with wand toys, puzzle feeders, and calm lap time all help maintain cognitive and emotional wellbeing. Keep their environment consistent (sudden changes can be more disorienting for older cats), provide warm comfortable resting spots, and spend regular quality time engaging with them.
