I started both meds on Monday night and the next morning my cat pooped three times which I thought was a great sign. Well, as far as I have seen, she hasn't pooped since so it's now been 4 days. It is possible, but not likely, that she pooped somewhere else in the house and I didn't find it since I have a labrador that is more than happy to clean up for her. I really don't think that is the case though since she used her litter box all three times on Tuesday morning with no problem. I've also been keeping a baby gate up so that the dog can't get near the box so I can monitor her movements.
By the way, I noticed that her appetite diminished at first on these meds so she was eating only about 1/4 cup of food for the first three days. I assumed that is why she wasn't producing waste like normal, but not that she's eaten her full 1/2 cup for the last three days, things should have normalized by now. At least I would think so. She is also acting completely normal, playing, eating and such.
I do plan to call the vet today but have a couple of questions for the group on all of this.
1. Has anyone had experience with Lactulose and if so, how did it work for your cat?
2. What day did it start becoming effective?
3. How long can a cat typically go without defecating before it's considered dangerous and requires an enema?
Thanks as always everyone!
