Hi David,
This fine folk have been back in the U.K. (Scotland I believe) for a while now...Just don't really understand the fuse over a few escaped ones. If disease was a worry...trap them...test them... then release if the tests are negative (or treat them.) Too many folks get their shorts in a know over these aquatic (and
native) rodents...They can be a nuisance when overpopulated...the U.K. and Europe would be lucky to have that problem again...It would mean thing are getting back to the way they had been before the "heavy hand" of humans out of control took over.
Regards,
j
