Among cats tested for cobalamin, which group showed more deficiency?

Explanation:
Cobalamin absorption depends on an intact distal small intestine and adequate pancreatic factors; when these are disrupted by disease, deficiency can result. Small cell lymphoma often involves the ileum with significant mucosal infiltration and damage, sometimes accompanied by pancreatic involvement, leading to greater impairment of cobalamin uptake. Inflammatory bowel disease can cause malabsorption too, but typically to a lesser extent than lymphoma. Therefore, cats with small cell lymphoma are more likely to show cobalamin deficiency.
