Reed, N., D. Gunn-Moore, et al. (2007). “Cobalamin, folate and inorganic phosphate abnormalities in ill cats.” J Feline Med Surg 9(4): 278-88.
The aims of this study were to evaluate the incidence of low cobalamin (vitamin B12) and folate levels in a population of cats that were suffering predominantly from diseases of the gastrointestinal tract, and to determine whether severity of disease related to the degree of deficiency. Of 103 cats in the study, 16.5% had low cobalamin levels and 38.8% had low folate levels. Supplementation of these nutrients in sick cats may be indicated more frequently than is currently thought.
