Feeding a pregnant cat properly is one of the most important things you can do to support her health and the healthy development of her kittens. Pregnancy increases a cat’s nutritional needs significantly, and meeting those needs ensures she remains strong, active, and ready for delivery and nursing.
In this guide, we’ll cover exactly what to feed a pregnant cat, how much and how often to feed her, and tips to make sure she and her litter thrive.
Why Nutrition Is Crucial During Pregnancy
A cat’s pregnancy typically lasts around 63 to 65 days. During this time, her energy and nutrient requirements increase steadily, especially in the final weeks. Proper nutrition supports:
-
Healthy fetal development
-
Maternal immune function
-
Proper milk production post-birth
-
Healthy weight gain without obesity
What to Feed a Pregnant Cat
1. Switch to Kitten Food
Veterinarians recommend transitioning a pregnant cat to high-quality kitten food, which contains higher levels of protein, fat, and essential nutrients. Look for labels that say “Complete and Balanced” and meet AAFCO standards for growth.
Choose wet, dry, or a combination — whichever your cat prefers — but focus on nutrient density.
2. Ensure High Protein and Fat Content
Cats are obligate carnivores, and protein becomes even more essential during pregnancy. Choose food with:
-
At least 30% protein (dry matter basis)
-
15–20% fat
-
Added DHA for kitten brain development
-
Calcium and phosphorus to support bone growth
How Much to Feed a Pregnant Cat
Your pregnant cat’s appetite will naturally increase — sometimes by up to 50% or more by the end of her pregnancy. Use this timeline as a guide:
-
Weeks 1–2: Maintain regular feeding amounts
-
Weeks 3–4: Gradually increase food volume
-
Weeks 5–9: Offer 25–50% more than usual
-
After birth: Continue feeding kitten food during nursing, as energy needs are even higher
It’s best to free-feed or offer several small meals a day, especially if your cat prefers grazing.
Should You Use Supplements?
If your cat is on a balanced commercial kitten food, additional supplements are usually not necessary — and in some cases, they can be harmful. However, if you’re feeding a homemade diet or have specific concerns, consult your veterinarian before giving supplements like calcium, taurine, or vitamins.
Hydration Is Key
Don’t forget about water! Keep fresh, clean water available at all times. If your cat prefers wet food, that will also help support her hydration levels.
Foods to Avoid During Pregnancy
Avoid giving:
-
Raw meat or fish (risk of parasites or bacteria)
-
Dairy (many cats are lactose intolerant)
-
Excessive treats or human food
-
Unbalanced homemade diets without veterinary guidance
Weight Monitoring
Some weight gain is healthy, but obesity can complicate delivery. Monitor her body condition closely and adjust food portions if needed. Your vet can help assess whether her weight gain is appropriate for each stage.
After the Kittens Are Born
Your cat will need to continue eating kitten food throughout the nursing period, which places even more strain on her body. Only return to adult maintenance food after weaning is complete (usually around 8 weeks).
Final Thoughts
Feeding a pregnant cat the right way is about more than just quantity — it’s about choosing nutrient-dense food, ensuring hydration, and avoiding harmful ingredients. With the right diet, your cat will be strong, comfortable, and prepared to bring healthy kittens into the world.
