It seems to me that people who are really interested in the physiological 
science as a test of feasibility of cryonics would not be disturbed by cat 

experiments and animal rights people are probably going to have a hard time with

cryonics anyway.  However, for those with genuine scientific interests, wanting
to believe but appropriately skeptical, the more disturbing aspect of the Suda 
work is that these experiments are now 40 years old and apparently there has 
been no consistent thread of research building on Suda's work.  Did he reach a 
dead end?  Did he die? What happened to his lab? What was the over-all 

objective of those studies? I, for one, would like to know the answers to these
questions. 
     I think an up-to-date concise summary of the research basis of cryonics 
which discusses the various animal models and their appropriateness is in 
order and might be helpful in persuading open science-oriented minds. I gather 

that contemporary work at CI and perhaps other places uses mice, partly because
mice are cheap and relatively easy to care for, but also, I suspect, because 
mice don't attract too much attention from animal rights people. In fact, mice 
are actually a pretty good model, being fellow mammals quite a long way up the 
phylogenetic scale.  When and if we can get good resuscitation data from mice, 
we will be well on our way to advanced perfusion protocols for humans.  Ron
