Poor girl. White feces can be a sign of dehydration. I would reocmmend ensuring you have easily accessible water for Snickers at all times. You should also consider getting a kitty water fountatin to encourage her to drink more. The bloody poop likely is caused by the really dry stool causing irritation as it is coming out. If the stools continue to be white after making these adjustments or if you see any more blood, then I would recommend getting Snickers seen by your vet. I hope that things improve soon for your pet Snickers. Best wishes and take care!

    Black tarry stool can be a sign of stomach or intestinal bleeding. Snickers could have a stomach ulcer or cancer in her intestines. I recommend an exam, blood panel and X-ray to see if they can find the cause of the weight loss and abnormal stool. Once they have a diagnosis then they can give you a treatment plan. Hopefully with treatment she will feel better and gain weight again. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Snickers.
