Licking my sweater

[Modra]

I've experienced some funny behaviour one of these days. My cat snatched my sweater from the back of the armchair and begun rolling in it and licking it, specially the armpits area (I guess the smell of sweat and perfume gave her a kick) . I'd describe the behaviour pretty similar to rolling in catnip. I didn't stop her, I just stood by until she got over with it and then she stopped and went about her regular business. The odd part is she doesn't react to catnip, I tried a number of times and she doesn't pay attention to it, but she seems all crazed up with my perfume (I'm sure is hormone free, I have it from a nature shop.
