Betsy,
Maybe you have contacted Carolina
Biological about this problem about heir cat specimens? It would be
interesting hear what the company has to say.

From: HAPS-L-owner@xxxxxxxxxxx [mailto:HAPS-L-owner@xxxxxxxxxxx] On Behalf Of Betsy Ott Sent: Tuesday, March 27, 2007 4:00 PM To: HAPS-L@xxxxxxxxxxx Subject: [HAPS-L] Cat preservation problems The cats we just received, which came from Carolina
Biological, just aren't as good as what we used to get. The muscles just
shred with blunt dissection, and it's taking hours to do a good job. 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.
