New Zealand White, Matted Fur on Cheek Area

[SheShedAcres]

I have a New Zealand White, approx. 7 months old and a first time momma. Her kits are 3 weeks old. I noticed a few days ago that the fur on what I would call her left cheek area seems matted and wet. My husband took her out of her hutch and I checked it over. No color, no obvious injury, just a small area to the left side of her mouth. She is eating and drinking fine, and taking really good care of her kits. It has me concerned as it has been this way since early this week. Any idea what this could be?


Thanks!

They could be rubbing their cheek on the water bottle

My rabbit Jeff does that
