Do not discontinue the Lactulose without the advice of the prescribing veterinarian. This may lead to constipation again. The dose and/or frequency of Lactulose will likely be adjusted by the veterinarian. In the meantime, a short fast followed by a bland diet fed in small, frequent amounts may help to resolve the diarrhea. You can discuss the use of veterinary probiotics, such as ProViable, ProStora or FortiFlora, with your veterinarian. These may promote gut health and aid in resolution of mild diarrhea as well.

Hello and thank you for reaching out to Boop by Petco. Yes, you can give lactulose orally. If he is a medium-sized cat, he can likely get 2 mL by mouth twice daily until his stools are softer. If he does not defecate for longer than 48 hours, he should be seen by a veterinarian right away. Constipation can progress to obstipation, meaning a cat is completely unable to pass the feces. This can lead to rupture of the colon and/or irreversible problems with the colon. I hope this is helpful.

While lactulose is a type of sugar, it will not make your cat overweight and it will also not damage your cat's teeth. Your kitty actually should lose some weight which will help with the constipation as well. If lactulose is working resolving the constipation then I would keep using it. Also make sure her water bowl is at least 5 feet away from the food bowl as cats do not like to drink water near their food.

Thanks for using Boop by Petco! Yes, as long as you have found the right dose where she is not having diarrhea and losing an excess amount of fluids then it would be ok to be used on a daily basis. Good luck and have a good night!

Lactulose has a wide dose range and can certainly cause diarrhea. I typically recommend adjusting the dose so that the stool is soft but formed like soft serve ice cream. You can try decreasing the lactulose by about 25%. If she is straining at all you should see a veterinarian, because occasionally dogs who are constipated can also pass small amounts of watery stool around the firm stool that is stuck.
