Signs and symptoms of kidney problems and CKD.

  • Weakness.
  • Weight loss.
  • Lack of appetite.
  • Bad breath.
  • Diarrhea (may contain blood)
  • Vomiting (may contain blood)
  • Dehydration.

If you notice any of these signs in your cat, see your veterinarian immediately.

If your cat has had kidney problems or has been diagnosed with Chronic Kidney Disease (CKD), you have likely been advised by your veterinarian to feeding your pet low protein cat food.

What to look for in low protein cat food?

Nutrition plays a vital role in managing CKD in cats. There are four core goals for managing CKD in cats:

  • Control the clinical signs associated with accumulating waste products in the blood,
  • Minimize problems with fluid and mineral balance,
  • Sustain adequate nutrition,
  • Modify/slow the progression of CKD.

What are the nutritional requirements for cats with CKD?

Increase Water Intake

Cats with kidney problems have decreased ability to eliminate toxins from their body through urine. Usually, cats with kidney problems have increased thirst to help the body get rid of toxins. It is crucial to provide increased water availability and interest.

Canned food

To increase water intake with food.

Water bowl

Change the water several times per day. Water fountain- to increase the cat’s interest in water consumption.

Food

By decreasing protein in your cat’s diet, you might be able to slow the disease down.

With a low protein diet, kidneys can work less on excreting protein waste products.

The recommended range of protein on a dry matter basis for cats with CKD is 28-35%. However, if protein intake is too low, CKD will start to break down muscle mass.

Phosphorus

Limiting dietary phosphorus in cats with CKD appears to help delay CKD progression, although the precise mechanism is unknown.

The recommended phosphorus range on a dry matter basis for cats with CKD is 0.3-0.6%.

Sodium

Dietary sodium levels are mildly restricted to reduce the workload on the kidneys.

Recommended Sodium on a dry matter basis is ≤0.4%.

Omega-3 fatty acids

Creates inflammatory properties to help CKD slow down.

It is crucial to address a cat’s kidney problem as soon as possible. Speak to your veterinarian if low protein cat food could benefit your cat.

If your cat has been diagnosed with kidney disease, it is crucial to start treatment right away.
