Hi All - I have a 12 -13 year old cat named Sydney. She is strictly indoors and weighs about 13lbs. I noticed she started vomiting more often, peeing outside her litter box, drinking lots of H20, and lethargic so I took her to the vet on May 5th. My vet said she was diabetic b/c her blood sugar was at 440/120, but had not gone into ketosis. She wanted to start her on Lantus insulin (1.5 units, twice a day). I gave her 1st shot the night of 4/11. This is where things get weird.... She threw up foam & clear liquid within 5 mins of the injection. I stayed up with her until 5 AM, I couldn't get her to eat, she had grown very weak, dazed & confused & threw up about 3 more times. I figured she was hypoglycemic so I tried giving her 1 tsp of Karo which made her thirsty. Took her to the vet the next morning. They kept her all day. They gave her a cerenia (anti-nauseous) and famotidine (peptid) shots. They took her glucose reading 4 times throughout the day (10a - 5p) and they read in the following order (220, 211, 98, 108). She had stopped throwing up, but they couldn't get her to eat. They were confused as to how her glucose was staying in the average range. So they sent her home hoping that being home will promote eating. She threw up in the car on the way home (I'm thinking due to car motion). I let her out the carrier and she wobbly walked upstairs & wanted to stay under the bed all night. Now its Saturday. Still can't get her to eat or drink, but she at least she is showing an interest. She sticks head in bowls but it's like she forgets how to eat & just won't open her mouth. (I have tried tuna, baby food, 2 types of wet, 3 types of dry). Called the vet & they are confused. They gave me an appetite stimulant pill and want me to give her 1/8 of the pill. Tried giving it to her, but she just kept spitting/drooling it out. My cat is the worst with pills. I am at a loss. I don't know what to do. I'm not even sure she has diabetes at this point. Her blood sugar is now normal. She is walking normal, no longer vomiting, but she won't eat or drink. It's going on two days. I don't want her to go into heptic shock. I also don't know if she got enough of the appetite stimulant. Has anyone experienced this or have any suggestions!
