Pearl limping again

No Pearl picture as she's not posing for the camera today. My parents have wood flooring in their kitchen and dining room. They have a large rug in the entry right after you step off the carpet into the dining room. Pearl discovered yesterday that if you run real fast from the living room and land on the rug you can slide it and yourself across the dining room floor. She tried this several times. And now she are limping on the same left front paw that landed her in the Pet ER right before the start of our trip. She doesn't seem to be as bad this time. She's walking, though with a limp, eating and drinking as usual. She even feels like playing with Stinkey. So we're hoping by morning that she'll be feeling better.
