Question about Lactulose...

It has been about a week since I started adding Lactulose to Snowy's wet food twice a day (bless my new vet for prescribing it to me!), and Snowy is slowly beginning to go back to his old playful self. I never realized that Lactulose is the alternative to Miralax until I started reading more about it on the forum and I am really glad that unlike Miralax, it is readily available in my country. However, there is a still a couple of questions I have about Lactulose that I was hoping someone could answer for me:

1) Ever since I add Lactulose to Snowy's wet food, I noticed that his pee has decreased quite a bit. I used clumping litter and it used to be really a really big clump every time I scoop it up (used to be once a day but he pees about twice a day now), but recently it became really small and more like a ball shape-wise (it used to be more oval-like in shape). I read that Lactulose helps to retain water in the stools to make it pass easier, so is less pee normal for a cat who is on Lactulose? He seems to be drinking the same amount of water after all.

2) I read that Lactulose is very high in sugar content. So is it really ok to continue giving it to Snowy on a daily basis from now on? Should I add even more water to his wet food or something?

3) Even with 2 ml of Lactulose twice a day (he had diarrhea when I gave him 5 ml each time so the vet told me to reduce it to 2 ml), Snowy only poops once every 2 days now. But his poop is softer and more elongated now (used to be quite dry and very round like pebbles). Should I increase the dosage until he can poop everyday, or is it ok for him to poop only once every 2 days?

Sorry for asking so many questions. Any advice or reply would be greatly appreciated!

Hi Christine!
I don't know about the Lactulose, I hope someone can answer your questions...
Have you tried the Search function, on the forum, to see if there are any threads that might have something on it??
So glad Snowy is doing better!

Are you certain that miralax isn't available in your country? Have you looked for it in its generic name, polyethylene glycol (PEG) 3350? For humans, peg 3350 is preferred over lactulose, so I'd imagine it to be similar to cats...

Just my thoughts, anyway. I'd ask your medical doc or pharmacist if they carry it.

Sharon: Thank you for always showing concern about Snowy. Yes I did read the threads about Lactulose in the forum but wasn't able to find answers to my 3 questions above.

Tabbcat: I live in Indonesia. I tried looking for Miralax all the way in Singapore and even they don't have it there. Lactulose is currently the best option I have

But I will definitely try looking for Polyethylene Glycol 3350 in Singapore on my next visit. Thank you so much for the info but for now I have to stick with Lactulose. It does seem to be helping Snowy. I haven't seen him this lively in weeks. He also doesn't seem to be depressed and inactive anymore.

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.
