Sir:- In September 1981 we published the results of leukaemia virus (Felv) testing of cats in New Zealand.(2) In addition we detailed recommendations for Felv testing of cats in this country. These recommendations were revised and updated in a second letter to the Journal in 1982.(3) Since then a further 465 cats have been tested at Massey University using the leukassay test (ELISA) (Leukassay F, Pitman Moore).
