I was pooperscooping the yard today, which I have to do periodically because our neighbor's cat likes to do her business there. I found two heaps of cat turds that were a rather funny color - an extremely pale yellowish-green. I know at least one of them, and probably both, were from Putzi, since I saw her "making one deposit". Other than the color, they looked normal. Putzi is 18+ (probably 20), and had a thorough examination with bloodwork in early February, according to her owner. She also hasn't had any change in diet, and is basically just overweight with poor hearing and eyesight, due to age. Any ideas? I have a vague memory of reading somewhere that pale stools could indicate liver problems.
