General Coverage for Senior Cats (8+ Years)

Senior cats (8+ years old) face a range of age-related health risks, including kidney disease (most common), arthritis, diabetes, hyperthyroidism, and dental disease. Treatment costs for senior cat illnesses range from $300–$4,000, with kidney disease being the most expensive (long-term medication, fluid therapy, and special diets).

While most pet insurance plans exclude pre-existing conditions, they cover new-onset age-related illnesses—making insurance a smart investment for senior cats without pre-existing issues. Premiums for senior cats are 20-30% higher than adult cats (1-7 years) but still cost-effective for covering major illnesses.

Kidney disease affects 30% of senior cats (10+ years old), with long-term treatment costs ranging from $500–$3,500 (fluid therapy, medication, special diets). Finding insurance that covers kidney disease is critical for senior cat owners to avoid unexpected vet bills.

We reviewed 12 pet insurance plans to find the best options for senior cats with kidney disease—balancing premium cost, coverage limits, and reimbursement rates.
