How to Bottle-Feed a Kitten: Formula, Technique and Care
Finding an orphaned kitten is stressful and urgent. Newborn kittens depend entirely on their mother, and without her they need warmth, food and help eliminating around the clock. Bottle-feeding is hard work, but with the right approach many orphans thrive. Always involve a veterinarian or experienced rescue as early as possible.
First, is the kitten really orphaned?
Mother cats often leave kittens for hours while hunting. Before intervening, watch from a distance for several hours if the kittens are warm and quiet. If the mother does not return, or the kittens are cold, crying or in danger, step in. Contact a vet, rescue or shelter immediately.
Step 1: Warmth comes first
Newborn kittens cannot regulate temperature. A cold kitten cannot digest food, and feeding it can be fatal. Warm the kitten slowly, using a heating pad on low under a blanket, a warm water bottle wrapped in cloth or a safe pet heating disc. Give the kitten a chance to move away from the heat. Do not feed until the kitten feels warm to the touch.
Step 2: Supplies
- Commercial kitten milk replacer formulated for kittens
- Kitten bottles with nipples, or a syringe if advised by a vet
- Soft towels and a clean warm nest box
- A kitchen scale for daily weights
- Cotton balls or soft cloths for stimulating elimination
- A notebook for feeding and weight records
Cow's milk, goat's milk and homemade recipes can cause diarrhea or be inadequate. See can cats drink milk.
Step 3: Prepare the formula
Follow the product directions. Mix with warm water, and prepare small amounts. Warm the formula to about body temperature, and test it on your wrist. Discard unused formula after the time on the label, and refrigerate prepared formula as directed. Wash bottles after each use.
Step 4: Feeding position
Place the kitten on its stomach on a towel, in a natural nursing position, with the head slightly raised. Never feed on its back like a human baby, since formula can enter the lungs. Gently tilt the bottle so the nipple is full of formula, and let the kitten suck at its own pace. Do not squeeze the bottle. If milk bubbles from the nose, stop, hold the kitten with its head down gently and let it clear, then seek vet advice.
Step 5: Burp the kitten
After feeding, hold the kitten upright against your shoulder and gently rub or pat its back until it burps.
Step 6: Stimulate elimination
Kittens under about three weeks cannot urinate or defecate without stimulation. After each meal, gently rub the genital and anal area with a warm, damp cotton ball or cloth until the kitten urinates, and sometimes defecates. Clean the kitten afterward, and dry it. Keep records, and tell your vet if there is no urine, or if stool is very loose or hard.
How much and how often?
Follow the label and your vet's advice, and weigh the kitten daily.
| Age | Typical frequency |
|---|---|
| 0 to 2 weeks | Every 2 to 3 hours, day and night |
| 2 to 4 weeks | Every 3 to 4 hours |
| 4 to 5 weeks | Every 4 to 6 hours, with gruel introduced |
| 5 to 8 weeks | Several meals, with solid food |
Kittens should gain several grams a day, about half an ounce in the early weeks. A kitten not gaining weight needs a vet.
Weaning
Around four weeks, offer a gruel of kitten wet food and formula in a shallow dish. Gradually thicken it, and reduce bottle feedings. By eight weeks, kittens should eat solid food. See kitten feeding schedule. Introduce a shallow litter box. See kitten litter training.
Health and hygiene
- Wash hands before and after handling kittens, and keep them away from other pets.
- Keep bedding clean and warm.
- Ask your vet about deworming, flea control and vaccines. See worms in cats and the cat vaccination schedule.
- Watch for diarrhea, dehydration and weight loss.
Warning signs
Contact a vet immediately if a kitten is cold, limp, not eating, crying constantly, has diarrhea, labored breathing or milk coming from the nose, or fails to gain weight. See the emergency warning signs guide, and use the US vet directory to find a clinic or a rescue group.
Common problems
Diarrhea or constipation. Often caused by the wrong formula, overfeeding or poor stimulation. Call your vet. Bloating. Feed more slowly, burp thoroughly and avoid overfeeding. Refusing the bottle. Try a different nipple, adjust the angle and make sure the kitten is warm. Aspiration. Milk entering the lungs can be deadly, so feed on the belly and slowly.
Finding help
Contact local rescues, shelters, foster networks and your vet. Many have experienced volunteers who offer supplies and advice, and some will take over care. Do not try to manage a very young orphan entirely alone without veterinary guidance.
Support
Bottle-feeding is exhausting. Reach out to local rescues, foster networks and your vet for advice, supplies and relief. If you cannot commit, find a trained foster. Socialization continues as kittens grow. See how to socialize a kitten and kitten growth and development week by week.
