Goodness, to walk in your house and see all that blood had to frighten your poor sister to near death.. I know when Boo's abscess ruptures, it made a terriable mess, blood everywhere and blood all over her.. Scared Rie to panic mode but she was smart and call the vet first, then called me. She made a appointment to bring her in the next moring but I told her "NO! Pack her up and take her then and leave her overnight".. Scared the pants off of me too, I was on the road, on my way home from the boat and knew it would be late night when I got home..I was already tired and knew I couldn't deal with it when I got home if she had gotten worse...still had about 7 more hours before I would have gotten home. That way, we BOTH rested that night! So, I don't have to imagine how your sister felt... I KNOW!
