#'''Decreased weight gain and low liver concentration''': Doong et al. found that kittens fed less than 4 mg/kg DM dietary copper showed signs of copper deficiency that included decreased growth rate and reduced concentrations of copper in the liver but no other consistent clinical signs<ref>Doong, G, Keen, C, Rogers, QR, Morris, JG, Rucker, R (1983). “Selected features of copper metabolism in the cat”. J. Nutr. 113:1963-1971. </ref>.

#'''Effects on reproduction''': In adult female cats fed low dietary copper levels (3 or 6 mg/kg DM as cupric sulphate) had an effect on reproductive efficiency, increasing the time for successful conception compared with control cats fed copper at 10 mg/kg diet. However pregnancy rates were unaffected<ref name="Fascetti">Fascetti, AJ, Morris, JG, Rogers, QR (1998). “Dietary copper influences reproductive efficiency of queens”. J Nutr. 128:2590S-2592S.</ref><ref>Fascetti, AJ, Rogers, QR, Morris, JG (2000). “Dietary copper influences reproduction in cats”. J Nutr. 130:1287-1290.</ref>. This study also reported that, plasma copper levels, unlike liver copper content, did not reflect dietary copper intake.
