Fur Slippers : Yay or Nay?

I seriously don't know what my position is on these Gucci mules/shoes/slippers, are they trendy or just overwhelmingly extravagant? 
This is precisely the reason I still don't own a pair- I simply can't make up my mind on whether I can pull them off or not. On the positive side, I can imagine my feet begging me to get them so they can stay warm and cozy, but there is a down side too. It's definitely a splurge and the idea of wearing "hairy" shoes just may look sloppy, if chic doesn't pan out. 

What do you think?
