Updated August 20th, 2016. Animal crackers are light colored and slightly sweet cookies.
Although animal crackers are made with a layered dough like crackers, they are sweet like cookies.
These differ from traditional animal crackers in flavor and assortment.
Although not usually called animal crackers, they are still considered animal crackers. ( source)
So can hamsters eat animal crackers at all?
Yes they can nibble them, but they are not a food that should purposely be fed to hamsters.
They are often too sweet or salty for hamsters to eat as a food.
