Switching foods, and noticing a difference in pop!

Hello!

I've decided to switch Nora's dry food for a couple of reasons but mainly because she always seems hungry. She gets 1/4 cup of dry for breakfast and 3oz of wet in the late afternoon (for the record, she will not tolerate a full wet diet - tried it, she refused, so she gets 50/50). Long story short, when we adopted her, she seemed to have a very sensitive stomach, so when we switched her from the nasty food she was on while in the shelter, we stuck with what seemed to agree with her stomach (which isn't the greatest quality). Now that she seems fully adjusted, I've experimented with food, and have realized that her stomach isn't as sensitive as I thought, so I have started to switch her dry food to Orijen as I hear a ton of great reviews about it! She loves the Orijen and it seems to keep her a little "fuller" longer which is great, BUT I'm noticing her pop has changed colour, and she isn't going everyday like she used to. She now goes every other day, and the pop is now dark brown. The consistency is still the same. Should I be worried about the lack of frequency? I heard that when they are on a high quality/high protein food, that their bodies absorb more nutrients, hence the decreased need to pop/eliminate. Thoughts?!

Her wet food is the same (rotation of Wellness, Halo, Nature's Variety, and some Blue Buffalo).

Here are the foods for comparison:

Well, cats are like people, some poop more often, some less often.  It's true that cats on a raw diet may only poop once every couple of days, and their poop their stools are a lot less in size.  But I've honestly not seen that happen with cats still eating kibble.  But then again, I never went from feeding something like Meox Mix to Orijin .  It makes since that feeding a higher quality food of any kind might lessen the amount going out.

I would say just keep an eye on her to make sure she isn't getting constipated, and as long as you don't see her really straining, or worse yet, see her scooting on the floor, she's okay with this schedule.
