I called and talked to the vet and she said it usually just means they are feeling a little under the weather...since Rockys eyes aren't doing it constantly, she doesn't see any need in seeing him just yet...she asked if any of it looked inflamed in the area and it doesn't so, she she said sometimes it just does that even if they are feeling a little down....she said cats can get depressed so I am wondering if that is the case..I don't know why he would be, but I will make sure and give him extra scritches and lovins today..
