how many chromosomes do cats have

Domestic cats have 38 chromosomes in total, arranged in 19 pairs.

Domestic cats have 38 chromosomes (2n = 38), which means 19 matched pairs in each somatic (body) cell.

Of these, 18 pairs are autosomes and 1 pair is the sex chromosomes (XX in females, XY in males).

Humans have 46 chromosomes (23 pairs), so cats actually have fewer chromosomes than people.

Dogs, by contrast, have 78 chromosomes (39 pairs), showing that chromosome counts can vary a lot between species.

So if someone on a forum asks “how many chromosomes do cats have?”, the accurate, up‑to‑date answer is: 38 chromosomes, in 19 pairs.
