Well the diarrhea boy seems much better. On Feb 9th we started him on a new food (Eukanuba Low resdidue). It is made specifically for cats with intestinal type problems. It took 2 weeks but as of Feb 23rd his poops looked normal. Well, that was 2 1/2 weeks ago and for the most part they remained soft but formed, which is a definite improvement. Unfortunately they are stil 90% left on the FLOOR! But, hey, clean up of a solid poop is 1000% times easier than a liquid poop, so I am happy.
