My 11 year old cat tested at 42 at 8:15 this morning. He was on dry kibble his whole life and when I switched him to wet he did refuse to eat for over 24 hours. He finally ate yesterday 2 times and this morning. I fed him at 7:30 am today. I normally inject him 3.5units at 8:30. I have not injected him today because of this reading. He was reading HI while on the kibble. Can someone tell me what to do PLEASE.
