Can guinea pigs eat leaf lettuce?

They can eat them.

Guinea pigs also like:

-cucumber (especially in the summer)

-parsley

-Apples

-dandelion greens

-grass from the yard (unless you use pesticides on yours)

-baby tomatoes

-melon (not too much since it's very watery)

-lettuce (occasionally - NOT ICEBERG)

They are very non fussy!! Guinea pigs very most FAVORITE food is carrots, which are also good for their teeth. You should also feed them orange slices, because the pigs need the Vitamin C.
