The brand 900mats produces large desk mats that are designed to be environmentally friendly. For example, they state: "Each mat purchase is carbon positive, the packaging is made from recycled paper and the mats are washable in a washing machine."
So if you mean a “Purple-ish Cat Mat” – presumably a version with a cat motif in purple tones – this mat would fit into the setup both aesthetically and functionally: generous space for keyboard and mouse + a decorative design.
