I don't think so because my cat had two liters of kittens and none of them twitched.
It depends on what type of cat it is
It can have 6-10 kittens at one time.
My Siamese cat had 7.
The number of kittens in a litter varies from cat to cat and even from litter to litter. It is most common for cats to have three to six kittens per litter.
Cats usually have 5-15 kittens if it is the first litter if they have 15+ then it may be a problem if the cat is under 3 years if it has 4 and down kittens then there may be hidden kittens
My client witnesses a hermaphrodite cat have kittens, it looks mostly male from the outside but delivered kittens.

'with two kittens' describe the cat. So, you should write 'is sleeping'. But if you mean that all three of them are sleeping, write 'A cat and his two kittens are sleeping'.
usually cats have only about 2-3 kittens in their first litter
kittens is little cat(s)
as many as she has nipples is a conservative estimate
