What area of OH do you live in?? I live in Upper Sandusky Oh. Do you live near a Pet Supplies Plus? They are several sizes or Meijer, I have seen them there too. I oredered mine off the net. I thing I got a 2 for one deal or something. If you go to Petsmart.com you can get $10 off your first order, that makes it reasonable!!
Let me know where you live!!
