Plush fetishes are like any other fetish...not necessarily something that interferes with life--though in extreme cases it can--but is an object or situation that one becomes aroused by. For me, I like Nazi uniforms, and the power and fear it comes with. It is likely that you enjoy the softness of the plushies, the way they feel, or perhaps it's the cutesy animal shape you admire. Whatever the case, let your gf know that they can never replace her.

Perhaps wrap her up in a soft fuzzy blanket when you cuddle. There are some rave attire she may be open to wear:



I wouldn't worry about your fetish unless it causes your gf too much grief.
