I have 6 kittens who are about 3 weeks old (no momma). They're currently on Kitten Glop as several of them stopped eating on Pro-botic, and a few more disliked KMR. They all like the kitten glop, and I'm supplementing with nutri-cal to make sure they get their vitamins.
I had to take them to the vet on Wednesday because none only 1 had pooped since I got them on Saturday. One was so constipated that she couldn't pee anymore (she's my runt). The vet helped her pee and poo, but since then it's a struggle for all of them.
I've tried Karo Syrup with no luck.
