Mittens
Yesterday, I was scooping my cat's litter box and noticed a fairly large amount of blood in one of her stools. Just a few minutes ago I found a spot of blood on my carpet. I turned her over to see if I could see anything abnormal and I noticed a very bright blue mark on her lower abdomen just beneath the surface of her skin, however, I am unsure if the mark is something new. Is this a legitimate emergency?
