What to consider for a Siamese cat
Senior Siamese cats (age 7+) often face dental issues, kidney concerns, and reduced mobility. Look for foods with glucosamine for joints, moderate phosphorus for kidneys, and high-quality animal protein to maintain lean muscle. Smaller kibble size can help with dental problems. Avoid excessive carbohydrates, as Siamese can be prone to obesity.
How we picked
We analyzed nutritional profiles, ingredient quality, and AAFCO statements for senior formulas. We prioritized brands with veterinary input, high protein-to-fat ratios, and added joint supplements. We also considered palatability for picky Siamese and consulted reviews from Siamese cat owners.
Senior Siamese cats benefit from diets with moderate protein, lower phosphorus, and added joint supplements to manage common age-related issues like kidney disease and arthritis.

Care, Cost and Maintenance
Transitioning Foods

Feeding Schedule
Offer 2-3 small meals per day to maintain energy and prevent overeating. Use measured portions.
