Hi all. I'm new to this and trying to get a message out in the hope of some useful advice. I have a sick 10 month old caiqu who is currently in vet care but we are unsure what is wrong. She recently had a very large rectal bleed, quite red and uncoagulated. The most recent addition to her cage was a manu mineral perch and I was wondering if anyone had ever experienced a problem with these or other type mineral blocks? Heavy mtal poisonining is unlikely but we have started treatment for this in case. Does anyone have any useful thoughts please??
