Health Considerations for Large Domestic Cats

Larger cats have specific health needs that owners should be aware of to ensure a long, happy life. Their size can predispose them to certain conditions, and proper care is essential to prevent issues.

Understanding these health considerations helps you provide the best environment and medical attention for your big feline friend.
