Can two cats be identical twins?
Identical or monozygotic twins are possible in kittens, but rare. Almost all kittens in a litter are not identical, even if they have the same physical appearance.
What are identical twins?
Identical (monozygotic) twins occur when a fertilised egg splits in two during early development resulting in two kittens who share the same DNA. This differs from non-identical (dizygotic twins) who have their own unique DNA. The worldwide incidence of identical twin births in humans is 3 – 4 per 1,000 births. We don’t tend to refer to kittens as twins, triplets, etc, in animals who give birth to multiple offspring, instead, they’re known as littermates.
