Chaster paralysis was originally described by Green Citation(1936) in fur-bearing animals being fed raw carp (Cyprinus carpio) which contained a high level of thiaminase. Subsequent reports of the condition in foxes, mink (Evans et al., Citation1942) and cats (Jubb et al., (Citation1956) were all associated with fish diets of high thiaminase content. However, more recently (Mayhew and Stewart, Citation1969; Loew et al., Citation1970; R. D. Jolly, pers. comm.) the condition has been recorded in animals receiving “normal” diets which have been shown to be, or have been suspected of being, thiamin-deficient.
