I have a grey squirrel that is 18 months old. i have been on vacation for 1 week and just came home to find her pretty sick. i have researched and i am sure she has MBD. I tried the tums in syringe and she would not have any part of it and she growled at me. she has never been aggressive towards me. she has bit everyone else in my house a time or 2 but never me.I was able to crush a tums up in peanut butter and she did eat half of that on a cracker. please can someone guide me here on what to do for her. I never wanted to be this attached to her. She was abandoned after a tree was cut down and she fell out and i planned on releasing her but that never happened she got to friendly to quick. I just went to cvs and picked up a bottle of "calcium magnesium & zink" I do not know how much to give her or even if this is good to give her. please help.
