Penny is being great so far save for one thing. At the moment she has the runs and though she is going to the litter box she's going out over the edge every single time. It wasn't such a big deal at first as she was spending alot of time in the basement where the two litter boxes are and that floor is easy cleanup but I put her in the bedroom to finish her food without Bosco trying to eat it or Reyna staring her down. I put a litter box in there just in case she had to go while eating and she's done it again, it's a white carpet too. Is there anyway to get the stains out? What can I do about her "overshooting" issue?
