Can Being Overweight Cause Pain for Your Cat?

Most cat parents know that extra weight can impact their feline's health, but few realize it may also lead to significant pain. If you're in St. Louis and share your home with an overweight or obese cat, it’s essential to understand how their weight might be affecting their comfort and quality of life.

Obesity in Cats: More Than Just Extra Pounds

Obesity in cats doesn’t just slow them down—it can put their bodies under constant strain. According to the American Veterinary Medical Association, cats are among the most common household pets in Missouri, and nationally, up to 60% of cats are considered overweight or obese.

When a cat carries too much weight, it puts added pressure on their joints and internal organs, increasing the risk for chronic pain. This pain may not always be obvious, but it can significantly affect their behavior, movement, and mood.

Signs Your Overweight Cat May Be in Pain

  • Reluctance to jump, climb, or use stairs
  • Limping or stiffness, especially after resting
  • Decreased grooming or unkempt coat
  • Changes in behavior, like irritability or hiding
  • Reduced appetite or difficulty using the litter box

If you’ve noticed any of these changes in your cat, don’t assume it’s just “part of aging.” Pain linked to obesity is often manageable—and even reversible—with timely care.

Common Conditions That Cause Pain in Obese Cats

Extra weight increases the risk for several painful conditions, including:

  • Osteoarthritis: Joint inflammation worsened by the stress of extra weight
  • Diabetes: May cause nerve pain and other complications
  • Lower back and hip problems: From carrying excess weight improperly
  • Urinary issues: Painful litter box trips due to discomfort when squatting

These conditions not only reduce your cat’s quality of life, but they can also become expensive and difficult to manage if not addressed early.

When to Seek Veterinary Help

Even subtle changes in your cat’s habits can signal pain. If you’re unsure whether your cat’s behavior is normal or something more serious, don’t hesitate to schedule an exam. A thorough evaluation can identify underlying issues and help your cat feel better—sometimes with just a few simple changes.
