My cat went to stand up at 2:30pm and fell over. Tested his BG it was 22. Immediately applied glucose gel to his gums. 30 minutes after his BG went up to 39. Tried to get him to eat, he won't eat. Syringe fed him, and he threw up. Tested BG at 3:30 pm and it was down to 30. Readministered the glucose gel. What do I do now? How do I get his BG if he won't eat? Help please.
