Cats’ Lifespan: What Pet Owners Should Know

by Jon Scaccia May 14, 2024

Owning a cat is a rewarding experience filled with moments of joy, affection, and companionship. However, it’s essential to understand that our feline friends have their own life trajectories and health considerations that can deeply affect their quality of life. A recent study provides illuminating insights into cats’ lifespans in the UK, offering practical information for cat owners to make better, evidence-based decisions.

Key Findings of the Study

The study compiled life tables based on 7,936 confirmed cat deaths in 2019 from veterinary clinics. It is the first research to provide life tables specific to UK companion cats, with insights into mortality patterns among different breeds, ages, and sex.

1. Overall Life Expectancy:
On average, a UK cat’s lifespan is approximately 11.74 years. The likelihood of mortality remains relatively low until age nine and increases rapidly thereafter.

2. Impact of Sex:
Female cats live longer, with an average life expectancy of 12.51 years, compared to 11.18 years for males. The difference may stem from various factors, including disease predispositions, lifestyle, and other risks.

3. Breed Status Matters:
Crossbred cats generally live longer than purebred cats by about 1.5 years. This difference narrows after the first few years of life but remains notable throughout their lives.

4. Longest and Shortest Living Breeds:

• Longest Living: Burmese and Birman cats live the longest, averaging over 14 years.
• Shortest Living: The Sphynx breed, with an average lifespan of 6.68 years, lives the shortest.

5. Influence of Neutering and Weight:
Neutered cats generally live 1.07 years longer than unneutered cats, and an ideal body weight is crucial for longevity. Lifespan decreases by 0.02 years for every 100-gram deviation from the average weight.

Practical Insights for Cat Owners

• Routine Vet Visits: Regular veterinary check-ups can help identify health issues early and prevent disease.
• Weight Management: Maintain a healthy weight to support longevity. Consult your vet to determine your cat’s ideal weight.
• Neutering Benefits: Neutering can contribute to a longer and healthier life.
• Breed Considerations: If you are considering a purebred cat, be aware of breed-specific health conditions.

Encouraging Life Table Literacy

This study advocates that cat owners and veterinarians develop life table literacy. Understanding the expected life trajectory allows owners to prepare for their cat’s changing needs over time, make timely adoption decisions, and discuss humane euthanasia in a more informed manner.

Discussion Questions:

1. How do you plan to adapt your cat’s care routine based on these findings?
2. What experiences have you had regarding breed-specific health issues?
