Arthritis, or degenerative joint disease, is common in older cats. Stiffness, limping, and reluctance to jump are often the first signs. While medication and lifestyle changes help, many pet parents ask: “What should I feed my cat with arthritis?”
The right diet can reduce inflammation, support mobility, and improve your cat’s comfort over time.
Understanding Arthritis in Cats
Arthritis occurs when cartilage in the joints wears down, leading to pain and stiffness. Risk factors include:
- Aging
- Obesity
- Previous injuries
- Genetic predisposition
Cats may show subtle signs like moving less, avoiding stairs, or grooming less frequently. Because cats hide pain well, dietary support is a crucial step in management.

Nutrition Goals for Cats with Arthritis
Cats with arthritis benefit from diets that:
- Reduce inflammation through omega-3 fatty acids.
- Support joint health with supplements like glucosamine and chondroitin.
- Maintain a healthy weight to reduce strain on joints.
- Provide balanced protein to maintain muscle strength.
Best Foods for Cats That Supports Bones Health
1. Prescription Joint Support Diets
- Hill’s j/d (Joint Care)
- Royal Canin Mobility Support
These diets include omega-3s, antioxidants, and joint supplements.
2. High-Protein, Low-Carb Foods
- Keep muscle mass strong while avoiding excess weight.
- Wet foods with chicken or turkey are easier to digest and hydrate well.
3. Foods Rich in Omega-3s
- Fish-based canned foods (salmon, sardine, mackerel).
- Veterinary fish oil supplements (EPA & DHA).
4. Supplements for Joint Support (Vet-Approved)
- Glucosamine & chondroitin – help protect cartilage.
- Green-lipped mussel extract – natural anti-inflammatory.
- Vitamin E & C – antioxidants that may slow joint damage.
Feeding Tips
- Portion control is essential. Overweight cats have worse arthritis symptoms.
- Use a feeding station with raised bowls to reduce strain.
- Offer smaller, frequent meals if your cat is less active.
- Consider warming food slightly—improves appetite in older cats.
Foods to Avoid
- High-fat foods that cause weight gain.
- Excess treats or table scraps.
- Raw diets without balance (risk of missing nutrients).
Lifestyle + Diet = Best Results
Nutrition alone isn’t enough—you’ll also want to support your cat’s joints with:
- Soft bedding to cushion sore joints.
- Ramps or steps for furniture access.
- Low-sided litter boxes for easy entry.
- Gentle playtime to keep muscles active without strain.
When to See a Vet
If your cat shows worsening stiffness, pain, or refusal to move, your vet may prescribe:
- Anti-inflammatory medications
- Pain relief
- Joint injections in severe cases
Diet works best when combined with veterinary treatment.
Final Thoughts
So, what should you feed cats with arthritis?
The best options are joint-support prescription diets, omega-3-rich foods, and balanced high-protein meals that keep weight under control. Supplements like glucosamine and green-lipped mussel extract can also help, but always consult your vet before adding them.
