I meant holes in the cover (I saw what you said earlier about her not actually tearing up the pillow, but the cover might be more fragile)
And actually, I just found an even better potential solution, assuming you've got a sewing machine or the patience to hand-sew a pillow -

It may be necessary to make a removable fabric cover in order to convince her to accept the newer, more sanitary pillow. Fleece is the safest for rabbits on the off-chance she chews a bit. If you go to Joann's, Hancock fabrics or Hobby Lobby to buy the fleece, go online and print out a coupon first in case it isn't on sale (the coupons can't be stacked with sale prices and can't be used instead if they're better than the sale):
Hancock fabrics -
http://www.hancockfabrics.com/viewc...vorites&utm_medium=email&utm_campaign=coupons (fleece is currently on sale)
Hobby Lobby -
http://www.hobbylobby.com/weekly/coupon.cfm (not sure about current sales)
JoAnn fabrics -
http://www.joann.com/coupon/ (fleece is currently on sale)
^ all of the above links are from my bookmarks; coupons for Hobby Lobby and JoAnn expire every Saturday, Hancock's expire less often - the bookmarks will automatically pull up the current coupon, but since it's after closing time on Saturday, you'll need to wait until tomorrow morning to print the new week's coupon for HL or JoAnn
I recommend against anti-pill fleece - I really don't like it. It's not as soft and honestly, I've never had issues with normal fleece pilling anyway. Between the apartment here and my house in San Antonio, I've got well over 200 yards of fleece and not one bit of it is anti pill
(I know, it's an obscene amount... it's for my online business, as it's the kind of fabric use for sugar glider pouches and cage sets... freaking JoAnn's wouldn't stop having amazing sales!)
Alternatively, if you made a new pillow the same size as the current one, you could gut the stinky pillow and use the outer fabric from it as a cover over the new one (which could also make the transition to the new pillow go more smoothly, since it would have that familiar smell and feel to it).
