Oh, OK, I remember now, you were posting information in another thread. During the holidays I had some time off and posted more than usual. Backlash was that it was hard to keep track of each kitty's history.
With regards to this list, from what I've read the fact that it's sugar doesn't matter and isn't connected with diabetes because it's indigestible, but maybe that's incorrect? I have not found the stickiness to be an issue since I mix it into his wet food, and honestly I despite being broke and spending thousands on this cat already, I can't let cost be a factor, I would like to do whatever is best for him.
From reading various threads on lactulose, it seemed to me that the chief complaint that worried me was that it was necessary to increase the dosage over time, though maybe this is also true for Metamucil or not that big a deal?
Right now I am mainly frustrated since the lactulose seems to be hit or miss, and the stress of constantly following him to the litter box and being worried whenever he doesn't poop is taxing.
Thank you also for the detailed description, Marc999. As for the slippery elm, I certainly have seen numerous recommendations for that and it's something I'm considering, but I guess I'm a bit scared about long term effects since it seems to be a relatively new treatment in use with cats and I haven't seen many veterinary sources recommending it. Please correct me if I'm wrong here because it definitely sounds like a good choice otherwise, I am just always suspicious of new treatments.
I found the same information re: lactulose sugar and diabetes. I think most people who stated the no sugar reason just wanted to stay away from sugars just in case, and includes me to some extent. The cost factor was more of an issue because people were thinking that if they're getting the same or better results from Miralax, why spend more? There didn't seem to be much downside to Miralax. If the lactulose isn't generating a good response I'd consider Miralax. Make sure he's not blocked first. Miralax will take 2-3 days and only works on stool that is forming. 1/4 tsp. 2x daily is the typical dosage, but many people recommend starting at 1/8 tsp. 2x daily and adjusting until there is satisfactory results. (this is called "dose-to-effect")
More medicine would needed over time for several of the remedies discussed. Off hand, that includes lactulose, Miralax, cisapride, and many fiber based solutions. After a while you do hit a limit as to how much medication you can safely give, and then a rather invasive surgery much be considered (invasive enough that some vets just won't do it). Nub doesn't have megacolon, though, right? This type of situation usually happens with megacolon kitties who have been on cisapride for several years.
I don't know for sure about the status of slippery elm in cats, but when I read about it, it seemed generally accepted. Have you been to the felineconstipation.org website? I believe it's mentioned there.
