Dark, black poop?

So for the past few weeks I've been dealing with all kinds of poop issues with my cat.

Last month my cat had diarrhea for about a week and a half, turns out it was probably a chicken allergy as once I switched to a different protein (venison/brushtail from Addiction) the diarrhea immediately stopped.

But now I've been noticing that her poop is very dark, sometimes to the point where it looks black. I don't think it's blood since, well, I don't see any blood anywhere and it doesn't smell (any worse than normal anyways), it also appears pretty solid and not "tarry". I don't think it's dehydration either because she eats nothing but wet food.

The vet did prescribe her antibiotics for a week to see if it would help with the diarrhea so I was wondering if that or possibly the change in diet be responsible for her the color of her poop?

I plan on giving the vet a call tomorrow regardless but I was hoping to get some opinions anyways so that I don't spend all night googling myself into a panic...

If those canned foods are darker meat, the poop will be dark too. I've fed venison, they are darker than chicken meat (like beef), but I also feed raw. I feel like canned foods usually ends up as dark brown, though.

You could also take in fresh stool samples to the vet and see if they can find out whether or not your cat does indeed have blood in her stool. Just because you can't see blood, it doesn't necessarily mean it's not present. If there happens to be an upper GI bleed, feces tends to be black. If the problem is in the lower GI tract (large intestine and near the rectum), the more likely you'll see the red. Hope it's not the case, but doesn't hurt to bring in a fresh sample to get the worry out of your mind.
