Breeding information below the pictures.
Lilac agouti is agouti with both brown and blue dilutions. In other words, it is blue cinnamon. This variety isn't by far a strikingly beautiful one, as the red / yellow pigment of a cinnamon is diluted into cream and brown into lilac.
In order to breed lilac agoutis, you will need to introduce the blue dilute gene to a cinnamon. Fastest way to do this is to breed cinnamon to lilac and then the resulting cinnamons to lilac, continuing with lilac agouti to lilac agouti crosses.
