Please contact the preserved specimen department. I know the folks in charge and THEY would want to know about your problems.

Is it a change in the fixative used?  Are all cats preserved in something different these days?  Or did we perhaps just get a bad batch?  This isn't the first time we've had this problem, so I'm beginning to think it's the preservative.  Last year, we tried leaving them in a vat of formalin, but it didn't help, as the cats were already fixed.  Any insight, or tips on what else to try, would be appreciated.
