 This research paper examined the prevalence of subnormal cobalamin levels and pancreatic disease in older cats, and studied their relationship with fat digestion. It found that 14% of the older cats had subnormal cobalamin levels, while 8% had a severe increase in feline pancreatic lipase, FPL, levels, and 2% had both alterations. Additionally, it was noted that these changes were not seen in younger cats. Furthermore, fat digestion was lower in those cats with subnormal cobalamin levels compared to controls. This suggests that decreased fat digestion may be associated with subclinical chronic gastrointestinal disease in older cats. Cobalamin levels are also a potential marker of gastrointestinal disease, which could be used routinely in older cats.
