YAY Mounds!!
I've gone with my sister to get kitty litter and food here before and I really like this place!
For any Chicagoan's who may read this, it is similar to a Petco, but priced like a PetsMart. So they are rather pricey..
My favorite thing about this store was the Adoption Center. They have this great big glass window that you can see all the available kitties they have up for adoption. And they also have a board with pictures and descriptions of available dogs from the local shelters they can bring in. I know PetsMart offers this as well, but it is not nearly as big or clean. :)~
