Mother cats need to be in a calm environment so that they can be stress-free and feel like they are keeping their kittens safe. Sometimes, stress can cause a mother cat to become aggressive or to not care for her babies properly. With that in mind, choose a private and quiet room of your home, away from the daily activities of your family, in which to situate the mother cat and her kittens.
It’s also important that they be kept away from other pets in the home. Other pets can be perceived as a threat by the mother cat and cause her to act aggressively to protect her young. If you have children and an active home, it may be best to foster when the kittens are four weeks or older. Sometimes mother cats will behave less defensively if their kittens are older.
Bringing everyone home
Set up your fostering room before you bring the mother cat and her kittens home. You should put the litter box as far away from the mother cat’s food and water bowls as possible, and provide a couple of different safe places where she can care for her kittens. A dark area equipped with a whelping box is ideal.
A whelping box is a box that is large enough for the mother cat to lie on her side slightly away from her kittens with all of the kittens in the box with her. The box should have sides high enough to prevent the kittens from wandering away, but low enough so it’s easy for the mother cat to come and go as she needs to. Lining the bottom of the box with puppy pads topped with newspapers will help absorb moisture. You can place an easy-to-clean blanket on top of the absorbent materials to give the mother cat and kittens a soft place to lie on. Please keep all these materials dry so that the kittens are not chilled by dampness. Do not place straw, hay or shavings in the area where the mother and kittens are kept.
When you bring your foster kittens and their mom home, put them all in the fostering room and close the door, allowing the mom to explore on her own. Give her a couple of hours before you enter her room and don’t be alarmed if it takes a few days for her to stop hiding.
Mom’s care of her kittens
The momma cat should take care of her kittens by herself for at least three to four weeks before she starts the weaning process for her babies. Each momma cat that you foster will be slightly different in her level of attentiveness, but there are three basic stages of nursing (see below). If for any reason your momma cat is not performing one of the listed functions, please notify the foster coordinator right away to evaluate whether the mom has a medical concern that needs to be addressed.
Kittens are born blind, but they can feel their mother’s heat and seek her out to begin nursing within two hours of being born. Mother cats should be lying on their sides to ensure that their kittens can find the nipples for nursing. Here are three stages of nursing:
- One to two weeks old: The mother cat initiates nursing by licking her kittens to wake them up and curling her body around them. After she wakes all of her babies, the kittens search for a short time period and then quickly latch on.
- Two to three weeks old: The kittens’ eyes and ears begin to function and they start to explore beyond the nesting area. This is when the kittens start interacting and playing with their mother. At this age, the kittens start to initiate some of the nursing and momma should comply by lying in the nursing position.
- Four to five weeks old: The kittens begin weaning and, in turn, the mother cat no longer initiates any nursing. If the mother cat still allows the kittens to nurse, it will be initiated by the kittens and can be lateral or upright nursing.
Occasionally, mom cats develop mastitis when their kittens stop nursing and begin to eat on their own. Mastitis occurs when the mammary glands inflame and harden, creating a very painful infection for the mother cat and causing symptoms such as a fever and listlessness. If you think your mother cat may have mastitis, call the foster coordinator on the next business day. This is not an emergency condition.
The mother cat will groom and lick her babies frequently for the first two to four weeks. She will stimulate her kittens to pee and poop, and will generally consume the fecal matter and urine. As the babies become more mobile, they will start to leave the nest and deposit urine and feces nearby, which is a good time to start introducing a couple of low-sided litter boxes (disposable tend to work best).
To ensure that the mother cat has enough to eat, give her access to both wet and dry food at all times. Food intake for a nursing mother can be two to four times the amount eaten by a cat who’s not nursing.
When fostering a momma cat, it is very important to observe her behavior daily and watch her interactions with her kittens to spot any problems. Unfortunately, 8 percent of kittens pass away because of inadequate maternal care. This can happen for many different reasons, some of which are beyond our control.
Problem behaviors in momma cats
Here are some details about problem behaviors in momma cats and what you can do about them.
Maternal neglect. Sometimes a mother cat stops providing care to one or all of her kittens. The neglect may be because of a birth defect or weakness in the kitten; she may just be trying to follow nature’s course, focusing her attention on the stronger kittens. Neglect may also happen because she is inexperienced or she’s in a stressful environment. Either way, that’s why it’s so important to make daily observations to ensure that she is caring for her babies. If she will let you handle the kittens, you should weigh each kitten once a day to ensure that they are gaining weight. If you notice that she is spending all of her time away from the kittens, is not grooming or nursing them frequently, or doesn’t respond to their cries, please call the foster coordinator right away.
Maternal aggression toward other animals. Aggressive behavior directed at other animals is common and expected from mother cats because they have a maternal instinct to protect their young at all times. With that in mind, please do not try to introduce her to the other animals in your home. As mentioned above, the mom cat and her kittens should have a quiet room of their own away from all other pets so that she and her babies can always feel safe. If she has seen another animal and becomes stressed or aggressive, it is very important to leave her alone and not try to comfort her. Give her 20 minutes or so to calm down and then check on her.
Maternal aggression toward people. Sometimes mother cats will act aggressively toward people. These behaviors may include hissing, growling, swatting and biting. Again, the mother is merely trying to protect her young. Generally, mom cats are evaluated for these behaviors before sending them into foster homes, but sometimes the behaviors develop later. If you have a mother exhibiting these behaviors, do not try to “correct” the behavior with a spray bottle or any type of punishment. She is only acting out of instinct to protect her babies and you could cause her aggressive behavior to escalate.
Contact the foster coordinator at the first sign of any of the above behaviors so the situation can be assessed.
Separating kittens and moms
If all of your foster animals, mom included, are healthy and friendly, there’s no reason to separate mom from kittens before they are eight weeks old. But there are a few medical or behavioral reasons for separating them earlier than eight weeks:
- As mentioned above, if the mother cat is showing signs of maternal neglect and is no longer caring for her kittens, the foster coordinator may decide to separate her from her kittens.
- If the mother cat is semi-feral or very undersocialized, the foster coordinator may decide to separate the kittens once they are eating on their own consistently and no longer need to nurse (around four to five weeks old). Separating them would prevent the kittens from learning feral behaviors from their mother and help them to become socialized, which increases their chances of finding forever homes.
- If there is a medical concern about the mom or babies, a veterinarian could make the decision to separate the kittens from the mother cat.
The kittens’ best chance at survival is to stay with their mom. Please do not separate your foster kittens from their mom for any reason, or attempt to supplement the mother’s milk with formula, without consulting the foster coordinator.
A healthy mother-kitten relationship
A mother’s direct interaction with her kittens includes the “brrp” or chirping calls she makes as she approaches them, as well as nuzzling and licking them to awaken them and to stimulate urination and defecation.
Initially, the kitten’s activities are restricted to crawling along the mother’s body and nuzzling against her to locate a nipple, often in competition with litter mates. The kittens suckle, lie still by the mother, move around near her and call out to her.
A call frequently given by the kittens is the cry associated with distress. It is given when a kitten awakens and is hungry, when a kitten’s movement is restricted (e.g., the kitten is trapped under the mother) or he becomes isolated and cold. The mother should answer the call.
Suckling is accompanied by kneading against the mother’s abdomen. It is thought that these kneading movements stimulate the mother’s milk flow, help to develop the kitten’s muscles and aid in digestion. The kittens may initially spend about eight hours a day suckling, but this activity decreases as they grow older.
As the kittens become older and more mobile, they become increasingly responsible for approaching the mother and initiating suckling. In the later stages of the weaning period (at about seven weeks old), the kittens become almost wholly responsible for initiating suckling. The mother may actively impede these efforts by blocking access to her nipples or by removing herself from the kittens’ proximity.
If you notice that the mother cat is neglecting her kittens inappropriately or showing any of the negative behaviors mentioned above, please contact the foster coordinator.
