Oh yes...my Celia's has had issues for years and is also on Miralax and cisapride daily. She's been on the Miralax for at least 4 years, the cisapride for maybe 3, and I've also been putting Homeopet's Feline Digestive Upsets drops in her water every day for several years. Overall, they have worked very well, although on occasion, she has still needed an enema. In fact, she just needed one this past Friday (not fun for either of us),
A little bit of plain canned pumpkin works really well for some kitties - mine won't eat it, but it's worth a try!
