I noticed Marishka's eye has been a little more 'goopy' lately, with brown crusties that I'm wiping off every single day. Because the fur around her eye is white, it is staining it a reddish-brown color. I called the vet, and she assured me that it's probably extra tears from allergies, and staining the fur. So, is there a wipe I can use to clean her eyes out better than I am doing? And should I get something that will help with the tear stains?
