http://www.smartgroups.com/message/readmessage.cfm? gid=1423922&messageid=8155&startid=8162 I have not seen much of a difference in respiratory depression with sevo in ferrets (or in dogs, but I have seen it in cats). Time to update your notes on the price of Sevo. I ordered some this week, and the current price is $226.80 for the 250ml bottle! That is the only size. Jerry Murray, DVM [Posted in FML issue 4444]
