my cats were playing and there was the usual cat yowls and unearthly screams and when they were done, mr.kitty cam up to me and demanded pets so i gave him belly rubs and felt something wet on his stomach. i check and there's a bunch of blood. i grab him and bring him to the sink to clean him up and i find more blood in the kitchen and my other cat is playing with a little thing of skin and hair. i shoo her away and it looks like a nipple. my cat just stole my other cat's nipple
