The cereal pieces are ring-shaped (hence “loops”) and come in a variety of bright colors.
They also come in a blend of fruit flavors (hence “froot”, a cacography of fruit).
However, there is no actual fruit in Froot Loops, they are only one flavor.
This has led to different methods of production in the UK. Kellogg’s introduced Froot Loops in 1963.
In the UK, Froot Loops are purple, green and orange.
This was due to the lack of natural colourings for yellow, red and blue, and are also larger in shape. (source)
So can guinea pigs eat fruit loops?
They can have one or two as long as they haven’t had any milk, sugar or any other food or additive added to them.
They aren’t a good food for them to eat a lot of though due to the amount of sugar that they contain.
However, do bear in mind that they hold no nutritional value for guinea pigs so are not recommended to be fed as part of their regular diet.
