Key takeaways:

• Engage in gentle interactions and monitor developmental milestones to support your kitten’s social maturity and health.

Finding a newborn kitten without a mom can tug at the heart—and spark a wave of questions. What does the kitten need right now? How can they be kept safe and healthy? It’s a big responsibility but also an incredibly rewarding experience. This tiny, vulnerable life now depends on human care. Though not easy and without risks, with guidance and support, it’s possible to help them grow into a happy, healthy cat.

As a stand-in caregiver, providing round-the-clock help, the right food, and a warm space are key for healthy growth. Your vet can help you determine the current status of your kitten and recommend the proper course of care. Here at PetHealthMD, we also offer trusted information to assist with basic care. Here are seven helpful steps to follow.

Step 1: Set up a warm and secure nest

A kitten needs to feel safe, warm and cared for—just like they would with their mom. Start by creating a cozy nest in a small box or basket lined with soft blankets or fleece. Place it in a quiet area away from windows or doors.

To help keep them comfortable, use a pet-safe heating pad under half the bedding so the kitten can move to a cooler area if needed. Keep the temperature between 85-90°F (29-32°C) during the first week, then slowly lower it to 80°F (27°C) by week four. A nearby humidifier may also make breathing easier.

Check the temperature regularly, especially overnight. A digital thermometer can help make sure it stays consistent. Swap out any damp blankets right away. If a kitten feels too warm or too cold, or if there are concerns about their space, contact a veterinarian.

Step 2: Master the feeding routine

Feeding is an important part of kitten care. Use a quality kitten milk replacer—never cow’s milk or baby formula. Prepare a fresh batch for each feeding and test the temperature on the wrist; it should feel warm, not hot.

Kittens usually need small, frequent meals every 2–4 hours, including during the night. Place the kitten on their belly and hold the bottle at a 45-degree angle. Gentle sucking and swallowing show the feeding is going well. 

Monitor feeding by watching for steady sucking and listening for soft swallowing. If a kitten seems uninterested in food, try warming the formula a little more or lightly rubbing their forehead. For growth tracking, see the guidance in the health section. 

If a kitten doesn’t eat after several attempts, contact a vet. It may be a sign of a health issue.

Step 3: Support digestive health and hygiene

Stimulation and digestion

During the first few weeks, kittens need help going to the bathroom. After each meal, use a warm, damp cloth to gently rub their lower belly and bottom. 

Daily care routine

Keeping a kitten clean helps avoid skin irritation. Use soft, fragrance-free wipes or cloths to clean their face, paws, and bottom gently. This also helps them feel safe and cared for.

Health monitoring

Watch for changes in how often they go to the bathroom or changes in stool. Keep bedding fresh and supplies clean. If anything looks unusual, a vet should be contacted. 

Step 4: Monitoring your kitten’s growth and health

Daily checks can help ensure a kitten is growing well. Weigh the kitten each morning before feeding. Healthy growth is around 10–15 grams per day. 

Physical growth signs:

• Gaining weight steadily
• Skin looks healthy, and breathing is normal
• Going to the bathroom regularly

Behavioral indicators:

• Feeding eagerly
• Periods of play followed by rest
• Calm behavior, soft purring

If there’s weight loss, tiredness, or constant crying, reach out to a vet.

Step 5: Start gentle interactions for social development

Building trust begins with short, calm interactions in a warm setting. Speaking softly and gently stroking the fur can help the kitten feel at ease.

Between weeks 4 and 17, begin slowly introducing safe toys, different rooms, and household sounds. Some kittens may need more time than others to feel comfortable.

Keep play sessions short and supervised. Use kitten-friendly toys to help build their coordination. Early playtime can help them adjust better to new situations later in life.

Step 6: Understanding developmental milestones

Watching for weekly changes helps track how the kitten is doing.

First week:

Expect lots of sleep and frequent meals. A full, round belly is a sign of good feeding.

Week 2-3:

Eyes start to open, and movement becomes a bit stronger. Baby teeth may begin to appear. 

Week 4-5:

Walking improves. Start adding wet kitten food to their routine while continuing bottle feedings. 

Week 6-8:

Kittens may start climbing and playing more often. Plan a basic vet check and begin offering different food textures.

Weekly check-ins:

Track their weight, energy, and how their fur looks and feels.

Signs of good health:

Bright eyes, steady energy, and weight gain. Any concerns should be discussed with a vet.

Step 7: Transition to a solid diet and independence

At around four weeks old, kittens often show interest in solid food. Start with a mix of warm formula and wet kitten food in a shallow bowl. Slowly make it thicker over time. Place a small water bowl next to it.

By weeks 6-7, softened dry food can be introduced. Watch for any signs of stomach upset or reduced interest in food. If anything seems wrong, contact a vet.
