How Many Kittens Are Typically in a First Litter?
Cats that are pregnant for the first time typically have two to three kittens per litter. This is somewhat less than the average litter size, which ranges between three to five. Cats that are bred often and cats that are in mid-life tend to have the largest litters.
Although these are average ranges, cats normally have anywhere from one to nine kittens per litter. The most kittens on record from a single litter is 19. Cats usually only have four sets of teats, so feeding larger litters is challenging. Very young cats and very old cats both have reduced average litter sizes.
