Hi! Thank you!! It's really a combination of a few things. She eats Stella and Chewy food and grain free treats. I clean her eyes every day with Aetero "Pretty Eyes," and I try to keep her face as dry as possible. The pictures can definitely be deceiving, she does still have some staining, but it's definitely fading as she gets older. I think it's true what they say about the stains kinda start to go away on their own after the first year because hers definitely seem to be. They used to drive me crazy when she was about 4-8 months old. She also gets cytopoint allergy shots occasionally if I notice she's really itchy and I think that helps too!
