Is there some reason we can't use нравиться in this case?
Have you used the proper forms of the adjective, noun and the verb?
The correct sentence should be "Рыжему (dative) коту (dative) нравится (3rd person sing.) есть рыбу"
what is the difference between use кот, кошке, кошка
кот is a male cat, кошка is a female cat. кошке can be dative or prepositional case of кошка.
Is there also a general term for either sex?
In English, "cat" does not refer to the sex of the cat. "Tomcat" is used less commonly. So I would assume that in Russian, "кот" is used less often and "кошка" is the typical term and doesn't refer to the sex of the animal, correct?
Said I needed the ь on ect.. Why? It marked as ok with a spelling error.
"ест" is the third-person singular conjugation of the verb; "есть" is the infinitive, which is what is needed here
These words never mean anything to me without examples. :/
Is third person singular like "he is eating"..?
Is this a tongue twister?
I don't think so.
Can you use рыбы?
No. In this case рыба is either a mass noun or a single noun. You can say рыб (the plural form in the genitive) if you mean the certain fishes, but it would sound awkward. We don't say that.
how would the construction be , if i wanted to use нравится instead of любить in this sentence ? thanks
Рыжему коту нравится есть рыбу. the cat would be in the dative.
