Rated 5 out of 5 by 6 reviewers.
Rated 5 out of 5by Keeps my cat running smoothly!My cat kindly takes it mixed in her food making it easy for me to dose her. She doesn't seem to mind the orange flavor and it's cheaper than the plain. 04/02/2016
Rated 5 out of 5by Good ProductIt's convenient and cost-saving to be able to purchase this larger bottle of Lactulose instead of running to the vet for the small bottles. I always receive the Lactulose in a timely fashion and consider it a good value. It does help my elderly cat Puffy as a stool softener, along with Cisapride, for her megacolon. 08/27/2014
Rated 5 out of 5by Very effective product that is also easy to dispense.After my cat was diagnosed with megacolon the vet prescribed Lactulose. 11/26/2013
Rated 5 out of 5by The worst product in the worldMy cat with megacolon was put on this product. It never worked and his megacolon got much worse. I found the megacolon users group on yahoo and they all recommended the use of Miralax instead. WOW, that worked. 08/22/2012
Rated 5 out of 5by Lactulose is great!My female dog was born with an unnatural dip in her colon and sometimes waste gets balled up and she would have to stretch herself out to loosen it or she gets constipated. Since using Lactulose, she has been able to "go" much easier without all the stretching. 09/26/2007
Rated 5 out of 5by Works as expected and the price is UNBELIEVABLY low!This was prescribed by my local vet for my 14-ish year old cat Samael, who has bowel problems due mainly to old age. He couldn't "go" and was so backed up that he almost didn't make it. Now using this product as prescrbed (2.5 cc's in the mouth EVERY 8 hours for the rest of his life... d'oh!) has made him quite regular again. PetCareRx has a GREAT price on this product! My local vet & the pharmacy they use charged me $40 for a 4oz bottle, while here at PetCareRx I can get a 16oz bottle for only about $16 and a couple bucks to cover shipping! $10 an oz VS about $1 per oz, WHAT A GREAT BARGAIN! Thanks PetCareRx, without you I don't know if poor kitty would be able to stay medicated and 'regular'! You have literally saved his life (and my wallet!) *This is a prescription item 02/06/2005
