Here's why:
* Litter size varies: The average litter size for domestic cats is around 4-5 kittens, but it can range from 1 to 10 or more.
* Factors influencing litter size: Several factors influence the number of kittens a cat has, including her age, breed, nutrition, and overall health.
* Single kitten births are rarer: While not unheard of, single kitten births are statistically less common than larger litters.
If you're wondering about a specific cat, it's best to consult with a veterinarian. They can provide more accurate information based on the cat's individual circumstances.
