Thanks for asking, guys

He's doing okay so far and finished having his bowel movement earlier, so that's good. It's really strange with his bowel movements, because sometimes all of the stool will be hard and other times, it's just the first little bit that comes out that is hard and the rest of it is softer

We're going to stop giving him the Laxatone all together since it doesn't help at all with his constipation anymore (though it did work before he was diagnosed with diabetes), and we're going to start adding canned pumpkin to his food to see if that helps; if it doesn't I guess the next thing we'd try is Miralax.
We're already adding the B-12 to his morning meals, so instead of adding the pumpkin to it as well should we add it to his nighttime meals, or maybe to a smaller snack during the day? How much would you suggest we add?
Unrelated, but Victor also just turned 11 recently

@Bama Kitty Mom (AL) Thanks for the suggestions about the syringes, I'll give it a try
