Here are my purchases at the dollar store: Dog rope chews, cat balls, giant jingle balls and chip bowls. The chip bowls make amazing igloos. I also get baby chew rings there as well.
Bottom level with the chip bowl igloo, 99 cent party streamers, and baby chew chains. The dollar store also has nice heavy crocks for food.
Chip bowl igloo with fleece from Big Lots ($2.50 for an entire blanket).
Top level toys and a hammock made from Big Lots Fleece.
