Club Crackers are a brand of crackers made by the Keebler Company.
They are somewhat similar in resemblance to saltines, but are rectangular and have 18 holes in a 3×6 pattern instead of the 13 holes in a 3-2-3-2-3 pattern that are on a saltine. Also, their edges are even, not perforated.
They have a buttery flavor and a large amount of fat, 3g per serving, not found in regular saltines. (source wikipedia)
So can hamsters eat club crackers?
Small pieces are fine for them to eat. They are not the best food for them as they are high in fat, but a few pieces will not do them any harm.
