My cat who is 14 years old is having a hard fînding a good stable number. She has dropped a ton of weight! Then she started to camp out beside the water bowl. She has always been a reclusive cat so this was clearly out of he normal. When we took her in on Wednesday her numbers where too high for them to register and clearly over 700. They gave her insulin and it dropped down too low and have her glucose. Again the next day but dropped the insulin. Same thing Friday but we brought her home. Tested her this morning and she was at 600. Gave her insulin(3 units). Checked her a bit ago and was 20! We have given her caro syrup. She is eating and drinking fine. She tends to sleep with her head on the water bowl. Vet said to drop her to two tomorrow. We are feeding her wet food that was on a low carb list of ok foods. Just wondered if anyone has experienced such highs and such lows before. Any advice? My poor girl can barely walk.
