How to say "ever" in this context


I want to say:

> I don't think cats are **ever** friendly.

The only "ever" I know is using ことがある but that doesn't seem appropriate. My
attempt without the "ever" is:

> 猫が友好的じゃないものと思います。

Btw, have I used もの correctly to make this into a statement about cats in
general?




I would personally suggest using 「決{けっ}して～～ない」 to say " _ **not ~~ ever ~~**_
" as in:

> 「ネコは決して人{ひと}なつっこい生{い}き物{もの}ではないと思{おも}います。」
>
> 「ネコは決して人なつっこくないと思います。」

「友好的{ゆうこうてき}」 sounds pretty stiff, so I changed it to 「人なつっこい」.

「じゃない」 is OK even though I used 「ではない」. 「じゃない」, however, can replace 「ではない」
only in my first sentence. In the second sentence, you _**cannot**_ say
「ひとなつっこくじゃない」 or 「ひとなつっこいじゃない」.

(「じゃない」, for some reason, is very popular among J-learners, but using it is
not as easy as many of them seem to think. For instance, if you said
「人なつっこいじゃない」, it has an _**affirmative**_ meaning --" _ **friendly, eh?**_ ".
the negative form of the i-adjective 「人なつっこい」 is 「人なつっこくない」. One cannot say it
using 「じゃない」. 「友好的じゃない」, however, is grammatical because 友好的 is a na-
adjective.)

I would not feel too comfortable if you used 「もの」 instead of 「生き物」 to talk
about animals.
