Yesterday morning, when I left for work, Max looked normal. In the afternoon, upon my return home, her right eye was puffy and red.
I tried to get her to tell me what she does during the day: street fighting? Boxing? Wrestling? Most likely, she attacked one of her toys that attacked her back.
Unfortunately, I couldn't get a good picture of this, but you can kind of see it in this video -- the redness above her right eye.
This morning, she's already shown improvement and I suspect she'll be back to normal when I get home from work tonight.
