This one is from my boy Jarvis, he's a super consitpated boy but he finally pooped and it was huge. So this is larger than normal sized but you get the idea:
And here is my girl Matisse, the brown squiggly things on the bottom of her cup is poo
It's worth it to note that their poop is going to look like what they eat. So if they eat brown/orange pellets, it will come out brown/orange. If you feed a pea (which I don't recommend) it will come out more greenish in color.
