That's how it is. A lot of kittens are bad. Too little, too bad. Ideal - by the number of active nipples.
In the first birth of Visa, there were 7 live kittens. It was never a fun attraction either. 6 kittens hanging on the nipples, one left in panic running, yelling "where my nipple is", and knocks everyone in turn. Not one first, no, it's too easy. He knocks everybody down... And then again all 7 kittens run and can not organize.
