"Синих кошек нет."

Translation: There are no blue cats.

[john.newbe]

But there is the breed Russian Blue.....

[emmanuelanajao]

No. It's Doraemon.

[Dimitrie_Grinwis]

There is Tom of course, from Tom and Jerry. :-)

[Cukt19]

sometimes he is blue and sometimes he is gray

[deepfriedmcrib]

I was surprised that it accepted "blue cats do not exist."

[DerAndereLerner]

There is/are just means that the subject exists.

Yet...

Ha! Thank you for that. Great story.

[KarinaYeva]

Funny you see this in a Russian course considering there is a cat breed called "Russian Blue"...

[emmanuelanajao]

Дораемон, пожалуйста читайте это. :-D

[ffirdafz]

Yep, not exactly blue, but bluish gray? Well that's what they call blue when naming cat fur's color ;)

[hohohohohoho]

'No blue cats' can't be right translation in some context?

[mehtap0800]

That is not a complete sentence in English, but the Russian seems to be a complete sentence.

[AzuLMc]

why Синих ? I do not understand that.

[SrMarien]

It's genitive plural, due to the inexistence of those blue cats.

[JeffCat6]

синяя точка сиамская?

[MasqueArt]

Duolingo certainly does not know about the theater festival here called Blue (tom)cat. - Modrý kocour

[MateusViccari]

Tip: All adjectives in genitive plural end in  -их or -ых

[xO.Lx]

What about doraemon? He was a blue cat...

[redactedname8732]

Может быть вы имели в виду Не бывать или не существуют

[jigojavra]

there aren't any blue cats not accepted

[STEFFIFI0902]

And green owls, neither :p

[Heto_Kadeyooh]

... Until the radioactive waste repositories start leaking ))

[Heto_Kadeyooh]

Alternatively: if there are blue cats in an area, move. https://www.youtube.com/watch?v=amn3kn0XPLQ&ab_channel=EmperorX-Topic

[chrischrispy]

Why wouldn't "There are not blue cats" count?
