My friend has a cat that has breed with its sisters. The female cat
has now had 4 kittens. They seem ok, but will they survive because
they have similar dna. The other sister is also pregnant.

Why don't you tell your friend to get the female cats spayed so this won't
happen?? (And the males neutered, as well!!!!!!!) If the kittens do make
it, they'll have things like extra toes, etc. But... THERE SHOULD BE NO
KITTENS.
Bop your friend over the head. And hard.

Friend is an idiot, but there won't necessarily be anything wrong with the
kittens. It depends on their genes and on whether there are any defects in
their bloodline for them to inherit. It isn't a given that they will be
damaged.
I know It isn't unusual to breed pretty closely when you are raising
purebred dogs as long as you have clean and varied pedigrees.

The cats should be spayed and neutered. There are already too many
pets in the world without homes.
I had a cat who was the offspring of his mom and his older
half-brother. He lived a normal, healthy life despite being the
product of inbreeding. Inbreeding doesn't guarantee genetic defects;
it just makes those defects more likely to show up if they already
exist in the bloodline.

They should all be fine, inbreading with cats is less dangerous than
with humans. All the cats should be spayed/neautered as soon as
possible.

David, if your friend is in the UK, and gets any kind of means tested state
benefit, then Cats Protection can help with the cost. The helpline number is
08702 099099. Cats can be neutered at six months old, earlier if there is a
pressing need.

If its a house with an intact Tom, 6-months is probably too late. My cat
Emily first came into heat at 4months, unfortunately the only one to notice
was Muddy (only about 6months old himself at the time) and the results were
inevitable, doh!

Actually, it's no more "dangerous" with humans - however,
animals (including people) who are closely related may have
recessive genes for undesirable conditions, which are much
more likely to develop if both parents carry the same gene.

Why would you wonder about their survival? Inbreeding may
make recessive genes dominant, but if they have good
heredity, survival shouldn't be an issue. However, there's
an easy way to PREVENT in-breeding! (It's called "neutering".)

Like others have already said, the kittens will probably be fine -
but, again like they're saying, tell your friend to get eveyone
speutered. There's already way to many unwanted cats/kittens in the
world, and a single unneutered mating pair of cats will produce a
staggering number of offspring in a relatively short time.
