I learned the following from others Duolingo Moderators:
Enkele Not double: enkele reis = single trip (not "enige reis") Not more than one: een enkele kaars = one [single] candle (not "een enige kaars"; that would translate to 'a lovely candle') Few in numbers: enkele mannen = a few men
Enige That where there is no second one of: zijn enige zoon = his only son (not "zijn enkele zoon") A small amount: enige vrienden = some friends
Paar A pair: een paar schoenen = a pair of shoes A few: Ik zag een paar dieren = I saw a few animals A couple of: Ik zag een paar dieren = I saw a couple of animals
Weinig Not much/many: Ik zag weinig dieren = I did not see many animals Few: Ik zag weinig dieren = I saw few animals Little: er weinig om geven = care little about it
I believe you should be careful with the use of the word 'enige' here. - it can mean 'some' when it is used as a determinant, though it is not usual. - when it is used as an adjective (as it is here) it means 'only' (a single thing).
In this sentence, since there is a plural afterwards (katten) the word to be used should be enkele.
This word can have more than one meaning with singular nouns. It can mean "only", but it can still also mean "some" and is commonly used in questions to mean "any".. I heard from someone else that it can even mean "cute". Context is so important. "Enkele" also has another meaning with singular nouns which is "single", but it can also mean "a few" with plural nouns. "Wat" and "een paar" are more commonly used, so "enkele" sounds a bit formal and "enige" more formal. Scroll down I gave someone else the site for Dutchgrammar.
I think we all need more explanation about when to use enige, paar, weinige, enkele etc. I am not a mind reader and i am getting cross at losing hearts when i have tried my best! The sentence in english can be interpreted in different ways according to context. But when there is no context?...
