Are hay cubes a substitute for loose hay for guinea pigs?
Hay cubes are compressed (squeezed together) hay and work best as a chew-friendly supplement or enrichment. Fresh grass hay should be the primary staple, with pellets on the side, so cubes should not replace free access to loose hay. Offer cubes alongside plenty of loose hay to keep fiber intake and foraging consistent.
My guinea pig's coat looks dull. Could their food be the reason?
A healthy, shiny coat is one sign a guinea pig's diet is working well, so a dull coat can be a sign to review their food. Make sure their routine centers on high fiber hay, and pair it with plain, vitamin C fortified pellets that use simple, clear ingredients.
