PARENTAL CARE AMONG ANIMALS 



it may be that their parental care is not quite so 

 striking as that of birds, where the laying of eggs 

 usually means nest-building and brooding. But 

 we have only to think of a cat and her kittens, or of 

 an otter and her cubs, to be assured that among 

 Mammals also parental care may reach a high 

 level. Indeed it is not too much to say that the 

 secret of the success of Mammals is very largely 

 to be looked for in the prolonged and many-sided 

 parental care.
