1) Lactulose, as you have already read, is holding water in the GI tract where it is being absorbed into newly forming stool (making the stool softer). The water in the stool is not being peed out. It's being pooped out. It is VERY important, however, that your cat does NOT become dehydrated, so definitely add more water to his canned food, assuming he'll eat it that way. Make his food as soupy as he'll eat.
2) Unless Snowy is diabetic, there should be no problem with him receiving lactulose on an ongoing basis.
3) As long as Snowy's stools are elongated and soft but firmly formed, it's fine if he only has one bowel movement every other day. Lactulose is a dose-to-effect drug, meaning that you can adjust the dose to achieve optimal stool consistency. If his stool becomes too soft, reduce the lactulose dose a little. If too small and hard, increase lactulose a little.
