I've had a couple of constipated cats in my life time and eventually things just stop working no matter what you do. I don't think you told us why your cat has been on lactulose in the first place. Five years of it is a long time. I had a cat with mega colon that I gave enemas to nearly every single day. When she pooped it would be one hard turd the size of your thumb. That's it. I kept her going way too long. That poor cat was suffering and I was really only thinking about myself. Tho nothing else was wrong with her medically other than mega colon. What happened was one Friday night I gave her the usual enema and nothing would come out. That poor cat strained the entire weekend and she couldn't go any more. I said good bye to her that monday. She was 18 years old and had a good life.
I just lost my Timmer three weeks ago to IBD and he couldn't poop in the end. Nothing worked but having an enema and manually pulling the stool out of him. I had that done. Have you ever had that done with your cat? I spent thousands of dollars on Timmer having him diagnosed only to find that none of the medications worked on his for his IBD. Sometimes our pets do not respond to meds. Either their bodies adapt and it no longer works and you have to find something else, or else it's just a situation where they don't respond. Same with people. Lots of people can have the same disease and one person responds to treatment and another person doesn't.
While I do believe our vets care, I also believe that some of them (not all) will run up a huge tab if you let them. Tests and more tests. Your vet should already know what the problem is after all these years. I don't mean to sound harsh so forgive me please.
Trust me, you are doing a fantastic job caring for your cat. I can tell from these posts how worried you are and it's frustrating when they don't go but your cat is going, just not daily like you want her to.
