Yes, I was reticent to switch from KMS after Nala’s first GI flare-up in February due to the lack of data and the concern about the calcium situation. My first two guineas both ate Oxbow and KMS with no problems. I am going in to this Sherwood ‘experience’ out of desperation and hoping for the best- so far she is tolerating it fine but like I said up top, she IS eating fewer pellets than before. She would not be a good study specimen at all, true, CageCleaner, as she had a complete diet overhaul at this time anyway and that’s probably the case for a lot of pigs or rabbits making the switch. I also wish there were more citations but am trying to make the best out of a rough situation.
