Buttons and biscuits are small-pet treats sized for a between-fingers hand-feed rather than a full snack, and the blueberry colouring here is doing the job of making that moment feel special.

They're baked from wheat flour and egg with sucrose for sweetness, coloured with EEC permitted colourants to give the blueberry look rather than built from actual blueberry. It's the same base recipe as Critter's Choice's other coloured buttons, distinguished only by the colourant used. It's the same base recipe Critter's Choice use across their whole range of coloured buttons, so the size and bake stay consistent whichever colourant is used for a given flavour name.

On the flavour. "Blueberry Buttons" describes the colour and shape rather than an ingredient — there's no blueberry, blueberry powder or blueberry flavouring anywhere in the composition, just wheat flour, egg, sucrose and colourant.

Who it's for: owners of rabbits, guinea pigs and other small pets who want a small hand-fed treat, and who don't mind that the blueberry is cosmetic rather than an actual ingredient.
