I'm diving into the old chest freezer and getting the rats ready for sale. I'm finding that most of my stretchers are identical in size for the most part. Here's the delima: The fur buyers like to see the big rats stretched on a wider wire. I have one stretcher out of 40 that seems to conform to the extra width standard. My question is who makes the larger rat stretchers? I would think that someone out there makes various sized rat stretchers, but there is only one size (7"?) offered in my catalogs.
