Kittens are usually orphaned when the mother is not able to adequately care for her kittens. This may be because she cannot produce milk or because she has behavioral or psychological abnormalities which prevent her from adequately caring for her kittens. In rare instances, the mother may actually not be present due to death, injury, or complications arising from a difficult birthing. Some kittens may be several weeks old before their mother becomes unable to care for them.
Successful rearing of motherless kittens requires a regular schedule of appropriate feedings, elimination, playing, and sleeping all in a safe and healthy environment. The principles of raising one orphaned kitten are not significantly different than those of raising an entire orphaned litter. In most cases, an entire litter is orphaned rather than a single kitten. Raising an orphaned litter in the complete absence of a mother is time consuming, but rewarding. To successfully raise an orphaned litter one must consider:
· Nutrition and weaning
· Temperature and humidity
· Disease prevention
· Nurture and socialization
Healthy kittens are plump and firm, warm, quiet, and sleep most of the time. Unhealthy kittens have poor muscle tone, initial high activity levels and cry a lot. If not assisted, they become weak, quiet, and comatose.
If at all possible, get the kittens to nurse from the mother in the first 12 hours to allow for ingestion of colostrum. Kittens are only able to absorb the antibodies from the colostrum for the first 24 hours of life. If the mother will continue to allow the kittens to nurse while she is made to lay still, that will decrease some of the work load on the caretaker. She may decide in a few days that she is willing to care for them.
If the mother is not able to nurse and care for the kittens, they will need to be bottle or a foster queen may be found. Queens will usually accept and nurse kittens that are similar in size (not necessarily age) to her own. Do not expect her to be able to handle two full litters on her own. Supplementation with a bottle will still be needed. Bottles for kittens are readily available and are the preferred method of feeding.
If the kittens are too weak to nurse from a bottle, consult a veterinarian.
Commercially prepared kitten milk formulas are readily available and are nutritionally balanced to meet the needs of orphan kittens. Do not use cow’s milk or goat’s milk.
Only make enough formula for one day of feeding and keep it in the refrigerator. Wash and dry the bottles and nipples thoroughly between feedings. Warm the kitten milk replacer in a pan of water until 98-100ºF before feeding. Mix well before using to decrease the risk of any hot areas of formula. Bottle feeding needs to be done very carefully to prevent aspiration of the formula, which can lead to pneumonia. Feed a kitten while he is on his belly, not on his back.
The first 24-48 hours each kitten needs 1 ml of milk per hour. Each day, increase the amount fed per meal by 0.5 ml until a maximum of 10 ml/meal is reached. Kittens will need 9-12 meals per day. During the second week, they should be on 5-7 ml per feeding. By the third week, they should be started on kitten gruel (mashed up kitten food, mixed with water and/or chicken baby food) 3 times a day and bottle feeding continued. By the fourth week, they should receive 4-6 bottle feedings a day plus the gruel should be fed 4-5 times a day. The middle of the night feeding can be reduced and then eliminated once they are eating gruel well. They can be completely on solid food by 7 weeks of age.
For the first 10 days, weigh the kittens daily at the same time to monitor their weight gain. Then weigh them 3-4 times a week for another 10 days. The common first sign of illness is lack of weight gain or weight loss. Each kitten should gain 50-100 grams per week. By 14 days of age, the birth weights should be doubled.
A newborn kitten is unable to urinate or have a bowel movement on his own. He lacks the necessary muscle control over these functions. A kitten must be stimulated to urinate and defecate. This duty is normally performed by the mother. Her grooming or licking of the kitten’s anal area will stimulate urination and defecation. Orphaned kittens must be manually stimulated by the owner to enable urination and defecation. The kitten must be stimulated after each and every feeding. Fortunately, this is easy. A cotton ball or piece of very soft toweling works well. Moisten it with warm water and gently rub the anal and genital area. Within one to two minutes the kitten will urinate and/or defecate. Kittens will need to be stimulated in this fashion until their bladder and bowel muscles strengthen, usually by 21 days of age. Most kittens will eliminate on their own by three weeks of age. Clean the kitten and you are done until the next feeding.
To remain healthy, kittens must be kept at the proper room temperature. Young kittens cannot conserve body heat or shiver to create heat. Supplying artificial heat sources such as an incubator, heat lamp, warm water pad, electrical heating pad, or special electrical heated mats designed for newborn pets will help kittens remain at the correct body temperature.
Regardless of the heat source, it is very important not to overheat or burn the kittens. Keep a thermometer in the kitten area to monitor the temperature. A simple 25-watt light bulb suspended over one end of a small box usually will supply sufficient heat. Keep a room thermometer under the light source to monitor the temperature.
Heating pads need to be monitored closely if used, as the kittens may be too weakened to move away from them and become burned. If a heating pad must be used, wrap it in a thick towel to protect the kittens from burns. For the first week, air temperature should be maintained at 85-90°. Over the next 3 weeks, decrease the temperature to 75°F. If the kittens are piled on top of each other all the time, they are cold. If the kittens are spread far apart, they are too warm. If they lay next to each other, the temperature is fine.
Kittens that are hypothermic (low body temperature) should be warmed slowly over 2-3 hours to a normal newborn temperature of 97°F. A normal body temperature should be obtained before feeding these kittens. Small shampoo bottles filled with hot water, wrapped in a towel, and placed next to the kitten work well and should be changed as needed. The kittens’ body temperatures are in the 100-102 degree range by about 4 weeks of age.
Orphaned kittens are at a higher risk of developing infectious diseases such as upper respiratory diseases. This is especially true of kittens that were orphaned without having received any of their natural mother’s colostrum. The colostrum, which is produced during the first 24 hours after giving birth, is especially rich in disease-protecting antibodies. Colostrum contains the antibodies, which when consumed by the kittens, provides immunity against many diseases. Kittens that did not nurse from the queen in the first 24 hours have not received colostrum and do not have good immunity. Because of the possible lack of immunity, properly vaccinating the kittens is very important.
Orphaned or hand-fed kittens should be raised together to aid in social development. They should be petted, cuddled, and played with by humans for 30-40 minutes a day over and above feeding and cleaning time. Kittens need mental and physical stimulation. If they have littermates, they will stimulate each other when moving. Soft stuffed animals put in the box can offer something to snuggle with while sleeping. It is important for the orphan kitten to have interaction with members of the household at 3-6 weeks of age. Remember, she is still a baby and must be handled with care, but you should start to introduce the kitten to noises, grooming procedures, new people, and pets. Early socialization and enabling the kitten to feel secure in her own environment will help prevent many behavior problems from arising in the future.
