Comment 1: I oppose adopting the 8th edition of the Guide, in part because many of the proposed changes that are purported to be for the benefit of the animals are not supported by any scientific evidence. For instance, I am not aware of any evidence to support the changes in rodent housing standards, or of any evidence suggesting that the health or well-being of laboratory rodents is at all compromised by use of the existing (7th edition of the Guide) housing standards. While any consideration of costs should be secondary to the primary concern for animal welfare, it is irresponsible to require costly changes to care that have no demonstrable benefit to the animals.
