Parent's love is the most wanted and necessary element for the baby's mental support. The baby is confident who feel secure to be in the arms of his parents. This is true not only for humans, but also for animals. Ecologists tend to separate animals into two groups based on their parenting – the r and K categories. The K category includes animals like elephants, cats, and us – animals that have relatively few offspring with longer gestational periods. Their fewer offspring require more focused care, and for a longer time – the sort of parenting we’re used to. Parents from the r category go for quantity over quality, with many offspring that grow quickly and individually have small chances of survival. If you needed any more proof as to what amazing parents we have in the animal kingdom, look no further than these loving moms and dads.
