Kittens sleep together in order to conserve body heat. Interestingly enough, most cat species only need to do cuddle for body heat in the first 4 days of their life since their bodies do not possess the capability to keep themselves heated. After the first 4 days, cuddling is seen more as a social activity used to express affection rather than for practical purposes.
