For the moment yes, as they are animals from two different species. Leap 
seconds form part of the current definition of UTC which is a time 
scale, even though not uniform due to the leap seconds. Leap days form 
part of a calendar and there are lots of different flavours to chose 
from. They are needed as the year isn't exactly 365 mean solar days days 
but about 365,2424. However if leap seconds are abandoned and nothing is 
done in between times there may need to be a real leap day in around 
86400 years as MST is slow by about 1s/year.
