I just picked up some black 1 gallon buckets at the dollar store about 10 inches in diameter. I cut them so that it was about 4 inches up from the bottom and then cut an entry like a mouse hole shape from a cartoon. I had to drag the lines a few times but I was able to cut them with a carpenters knife. Cost me $4.32 and about an hour for 4 hides. Here is a photo.
