Frequently Asked Questions
Is Purina Pro Plan or Royal Canin better for senior cats?
Neither is better for every cat. Pro Plan 7+ targets cats from age 7 with higher protein at a lower cost, while Royal Canin Aging 11+ targets cats over 11. Match the food to your cat's age and health with your vet.
Do senior cats need less protein?
Not necessarily. Healthy senior cats generally need good quality protein, but cats with kidney disease may need a different diet. Ask your vet before changing foods.
Should senior cats eat dry or wet food?
Wet food adds water, which helps many senior cats, and dry food is convenient. A mix is common. Your vet can advise based on your cat's health.
How should I switch foods?
Change gradually over about a week by mixing increasing amounts of the new food into the old, and watch your cat's appetite and stool.
