Thank you for your advice. I checked again after 1 hour. It was 182. I decided to skip his shot since I had to leave for a curb pickup at the grocery store. I will test again before I feed him.
I would like to know if the raw pancreas I have been feeding him for the last 2 months could cause this rapid decrease. I noticed that for the last 3 weeks, Phoenix has been having regular bowel movements every day. Prior to this, for the last 3 years, he only had a bowel movement every 3 days. These would be very firm and dry. I would give him olive oil or femalt to lubricate his movements. Now, I don't need to do this.
Your opinions would be appreciated. I rely on all of you for your excellent advice and thank you.
