Hi, it's almost 3 am now and I don't know whether to give my cat her insulin jab. She usually has it at/around 11pm but threw up just before I was about to jab her. I took a glucose reading (using human glucose meter in the uk) and the reading was 16.6 mmol/L. It's usually in the mid-20s + when I give her a shot. I then tested 10 mins later, with a reading of 18.1. I thought that it would rise and hope to be able to give her the shot but then I tested again just under 2 hrs later and it was 16.1. After this, she was sick again but then ate a bit soon after. Her reading was 19.5 and again, hoping it would increase, tested her about 20 mins later and it's 18.6. I realise testing her after 15 or so mins may not be helpful but as I said, it's almost 3 in the morning and I really need to get some sleep! But at the same time, I don't know whether to inject my cat with her insulin. I don't want her to be ill in the night. She's not been sick since last time, which was almost 2 hours ago, and she's had a bit to eat and drink. She also seems completely fine now in herself. Any advice? Her insulin dose is 1.5iu. I am planning on phoning the vets first thing later on. Thanks.
