How Often Should a Hamster’s Cheek Pouch Be Cleaned?

A hamster’s cheek pouches rarely need cleaning; it cleans them itself unless inflamed, when you must clean and treat. Pouch inflammation is common if food is hard or sharp.

The pouch does not secrete saliva, keeping food dry and mold-free, but it has many blood vessels, so hard or sharp food can injure and infect it.
