Essential Tips for Bottle-Feeding Orphaned Kittens with Success

Bringing an orphaned kitten into your care is a deeply rewarding experience—but it can also be overwhelming, especially if you've never bottle-fed a kitten before. This guide is here to help you provide the life-saving care these tiny, fragile lives need to thrive.

When to Bottle-Feed

Bottle-feeding is necessary when kittens:

• Are under 4 weeks old and have no mother

• Are not nursing from their mom or are being rejected

• Are too weak to latch or nurse effectively

If you're unsure of a kitten's age, a good rule of thumb is this:

• 0-1 weeks old: Eyes closed, ears folded

• 1-2 weeks: Eyes open, ears unfolding

• 2-3 weeks: Beginning to wobble and crawl

• 3-4 weeks: Starting to walk and teeth may appear

Supplies You'll Need

• Kitten-specific formula (like KMR or Breeder's Edge)

• Kitten bottles or syringe with a nipple (We like Miracle Nipples)

• Kitchen scale (to track kitten weight)

• Towels and tissues (for cleanup and helping kittens potty)

• Heating pad or Snuggle Disc (to keep kitten warm)

Never use cow's milk! Kittens require a special formula designed for their nutritional needs.

Feeding Frequency by Age

Newborn to 1 Week Old: Kittens in this age group should be bottle-fed every 2–3 hours, including overnight, totaling 7–8 feedings per day. Each feeding should provide approximately 2–6 ml of kitten formula, depending on the kitten's weight.

1–2 Weeks Old: As kittens grow, they can be fed every 3 hours, with each feeding consisting of about 6–10 ml of formula.

2–3 Weeks Old: Feeding intervals can extend to every 3–4 hours, with kittens consuming approximately 10–14 ml per feeding.

3–4 Weeks Old: Kittens can be fed every 4–5 hours, ingesting about 14–18 ml per feeding. At around 4 weeks old, they may begin showing interest in wet kitten food or chicken baby food, signaling the start of the weaning process.

4–5 Weeks Old: Feedings can occur every 5–6 hours, with each feeding providing 18–22 ml of formula. Kittens should be introduced to a gruel made of wet kitten food mixed with formula, gradually transitioning to solid food.

5–6 Weeks Old: By this age, kittens typically consume solid food and may no longer require bottle feeding. They should be fed four times a day, with access to fresh water at all times.

Key Considerations

• Monitoring Weight Gain: Weigh kittens daily to ensure they are gaining weight appropriately. A healthy kitten should gain approximately 10–15 grams per day.

  
  

• Avoid Overfeeding: Do not exceed the kitten's stomach capacity, which is roughly 4 ml per 100 grams of body weight. Overfeeding can lead to aspiration, diarrhea, and other health issues,

  
  

• Nighttime Feedings: Healthy kittens over 48 hours old can usually tolerate slightly longer intervals between nighttime feedings, such as every 3–4 hours, without adverse effects.

Note: Every kitten is different. Watch for cues like suckling strength and signs of fullness.

How to Bottle-Feed Safely

1. Warm the formula to just above body temperature. Test on your wrist, where you should just barely be able to feel it.

2. Hold the kitten belly-down on a flat surface, never on their back (risk of aspiration).

3. Insert the nipple gently into the kitten's mouth and let them latch.

4. Allow them to suckle at their own pace without squeezing the bottle.

5. Burp the kitten by gently patting their back afterward.

6. Wipe their face clean with a soft cloth or tissue.

Warning Signs to Watch For

Contact a vet or kitten rescue if you notice:

• Refusing to eat

• Coughing, choking, or milk bubbling from nose

• Bloated or hard belly

• Pale gums or cold body temperature

• Diarrhea or constipation lasting more than 24 hours

Don't Forget to Help Them Potty

When kittens are young, their mom usually helps them pee and poop. After each feeding:

• Use a warm, damp cotton ball or tissue to gently rub their genital area.

• They should urinate after every feeding and poop about once daily.

Creating a Safe Feeding Environment

• Keep kittens in a draft-free, quiet room

• Use a heating pad set on low under part of the bedding

• Sanitize bottles, nipples, and hands before each feeding

• Monitor kitten weight daily to track growth and flag issues early

Graduation from Bottle-Feeding

At around 4-6 weeks old, kittens will begin transitioning to solid food. You can start by:

• Offering formula-soaked kitten kibble or gruel

• Gradually reducing bottle feedings

• Introducing a shallow dish for independent eating
