我家后面的野猫吃自己的孩子

飘逸手语

我家后面有两只野母猫, 一只是有些许条纹的,一只是黄白猫..

之前条纹猫吃了自己的孩子...
我就上网查, 发觉有人经常去看,或者去动过小猫, 母猫就会吃掉自己的孩子...
这次则轮到黄白猫吃自己的孩子了,
我想应该没人去动过它的孩子吧? 而且它生了孩子也不是一两天的事了,大概都有两三个星期了..
现在还剩一只小猫而已, 我怕那只母猫又会去吃...
原本一直超可爱的小猫,现在变成头只剩一半,肠子都露出来的尸体,实在让人心酸...
我想问:
是母猫太饿了吗? 还是母猫因为有人去动过小猫而感到不安全?

Females Killing Kittens
Kitten-killing is more oftenseen in females, simply because the tom is usually absent from thenest. There are numerous reasons for this behaviour.



As in tomcats, some femalescannot switch off hunting behaviour in response to the presence ofkittens. Some have poorly developed maternal instincts or they may havea hormonal imbalance so that the maternal behaviour is not triggered bypregnancy and kittening. Because the kittens may inherit this as agenetic trait (hypothetical but very feasible), it is wise not breedfrom such females again - not just to avoid the tragedy of seeingkittens killed by their mother, but to avoid the problem becoming morewidespread. Females which haven't given birth may treat kittens born toother females as prey. Pregnancy and birthing cause hormones whichgenerally trigger maternal instinct. A female without kittens has notgone thorugh this process and the size and sound of the kittenstriggers her hunting instincts.


Some kittens are born withabnormalities that humans cannot detect. For this reason they may notthrive, they may even act or smell 'wrong' to the queen. Where one ortwo kittens are either killed or abandoned, these kittens are oftenfound to be somehow 'faulty'. The mother simply does not want to wasteenergy on raising kittens that have little chance of survival. Inaddition, she has expended a lot of energy during pregnancy and she mayeat all or part of some of these kittens in an attempt to recoup someof those losses (just as she eats placentas) and to dispose of'carrion' that could potentially lead predators to her nest. The samegoes for kittens which have an illness - she can smell the problem,humans cannot.


It is well known that a mothercat may kill kittens if the nest is disturbed, especially if she isconfined and cannot move or hide her litter. This is attributed to afrustrated 'protection' instinct. Unable to protect her kittens againsta perceived threat, she kills them in a futile attempt at protectingthem. Perhaps instinct tells her that it is better to kill offspringherself and make good her own escape than to attempt to defend themagainst insurmountable (in her view) odds and possibly endanger herselfin the process. A few mothers have accidentally killed kittens bytrying to push them underneath a doorway in an attempt to movethem to a new nest and some over-anxious but non-confined queens havekilled kittens as a result of maternal incompetence or perceivedthreats to the nest. These mothers are generally either desperate orinexperienced or both. A few nervous queens are disturbed enough by thescent of a tomcat nearby that they will resort to the eat-is-protectmechanism.


Stressed mothers may simplydecide to cut their losses. Perhaps finding that they cannotsuccessfully rear or save their own kittens, it becomes preferable totry again at a later date or in a more favourable/safer location.However, she has invested a lot of effort in pregnancy and sucklingthose kittens (and in hunting for food for older kittens) so she eatsthem in order to reabsorb some of that energy investment. Byreabsorbing the nutrients they gained from her, she will more quicklyreturn to breeding condition and may successfully raise kittens laterin the same breeding season. Some mothers will simply abandon kittens,but in doing so they lose whatever investment they put into partlyrearing the offspring and might not breed again until the next season.This may also explain why some females kill some, but not all, kittens- by reducing the number of kittens in their litter, they increase thechances of successfully rearing their surviving kittens.
Sometimes she will kill thekittens because they have been handled by another person or animal. Herown scent has been obscured and she either no longer recognises them asher own or she feels threatened and unable to escape. They eitherbecome prey - in size, sound, smell and movement - or she attempts to'protect' them by the last resort method of killing them. A female thathas prevously been in an abusive situation may be anxious with kittensand may kill them as a result; stress seems to over-ride normalmaternal instincts.


Where several litters havebeen born in one colony it is not unknown for one queen (generally themore dominant one) to either kill her rival's kittens or to 'kidnap'them. This may enhance the survival prospects of her own litter; it mayremove the genetic competition from the other queen; it may be that thepredatory queen's maternal instincts do not extend as far asrecognising the other kittens as something other than prey oralternatively it may be that her attempts to kidnap the kittens andraise them as her own (over-developed maternal instinct?) result in theaccidental death of the kittens as one queen tries to kidnap them andthe other tries to defend them (even to the point of killing themherself). In a number of such cases the queens may move into a singlecommunal nest and take turns in nursing the kittens, but in other casessome of the kittens (usually the smaller, more fragile, ones or thoseof the less dominant queen) die. The kidnapping of offspring is betterdocumented in dogs, but has been observed in cats as well.



Another cause of kittenkilling is rare, but not impossible. An inexperienced or over-anxiousmother may clean her kittens excessively. In some cases a queen hasbeen known to bite off a kitten's paw, tail or ear due to excessivecleaning behaviour when the kitten is small and relatively fragile. Ina very small number of cases, her efforts at cleaning (and restraint)are forceful enough to kill a tiny kitten. In an attempt tohygienically dispose of the body she may consume or partially consumeit.
Finally, kitten deaths occurnaturally and for diverse reasons. Many queens will dispose of the bodyby removing it from the nest or moving the nest away from it. Anotherway of disposing of carrion is to eat it. Where the kitten is onlypartially consumed it may appear that the mother has killed it even ifshe is simply trying to dispose of a potential predator-magnet.
