We have two kittens that we have been bottle raising since they were 2 weeks old. They were given to us to care for when the mother died. They are now right at 4 weeks old and are starting to poop big normal sized cat poop instead of the watery stuff. Unfortunatly without a mother cat to clean them they have poop all over them from walking through it in the "nest box" I have cleaned them as best I could with baby wipes, but they need a real water bath to get the dried poop out of their fur. Is it safe to give kittens that young a water bath?
