My diabetic cat is unresponsive and lethargic. Is it an emergency?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 8 years old | 12 lbs

I came home and my cat is very lethargic. He can't keep his eyes open. He's diabetic, but his BS is normal for him 355. He ate well and has used the litter box today. But he is not very responsive at all.

It is extremely concerning that Simba is not responsive. A blood glucose of 355 is very high, even for a diabetic cat. Given his unresponsiveness, I recommend taking Simba to an emergency veterinarian immediately. There is a chance that he may be experiencing diabetic ketoacidosis (DKA), which can cause massive shifts in the blood electrolytes, which can lead to seizures or changes in the heart. I hope that all goes well for Simba!
