As best as I can discern (thanks for the Google reference, Kathy), the eye gunk/diet relationship remains anecdotal. Unless your pet has a medical issue, eye gunk is just annoying and diet change may or may not improve it. Just like Jackson's mom is always saying, what works for one may not work for another. What does seem clear to me (no pun, here
) is we must keep our furbutt's eyes clean and dry to prevent bacterial infection from setting in. It all comes back to warm water, a cotton ball and consistency.
