Has anyone had good luck with VetBasis Hairball Gel? It was recommended to me by someone on this site because of my cat's chronic constipation problems. It has no petroleum jelly. I ordered some after reading the testimonials on their website, but in the mean time just wondering if anyone has tried it with good luck. Mitties is exhibiting signs of being plugged up again. I don't get it. She does good for about 3 weeks then slowly her stools become smaller and smaller until she stops going altogether. She didn't go at all yesterday unless you count the marble-sized terd that was in there. She's on Wellness canned and dry, but I'm thinking I may switch her to all wet. The vet said she does not have megacolon. I've tried EVERYTHING in the book for constipation, so I'm really hoping this hairball gel works better than laxatone did. She hated it and it was a giant mess. Sorry all my posts are pretty much about constipation problems...but I just can't seem to find a combination of food/medicine that actually keeps working. It always comes back! Poor girl... I do have some enemas on hand just in case though.
