5/15/18 Simon (I'm sorry, Idk what AMPS means) Good evening, Simon is a 13 y/o male. Diagnosed with diabetes by his vet 5/7/18 (a week and a day ago). I IMMEDIATELY switched him to an all canned, low carb diet; keeping between 250-350 calories(as advised by a veterinarian friend). While waiting for his insulin(Glargine/Lantus) and needles to arrive, he seemed to be urinating less, but still meowing a lot for food. I've been trying to get him used to a set schedule, to prepare for the upcoming injections. This morning was normal, with vocal requests for food. Went to the vet so I could do a cpl practice shots into a towel, Then with a fresh needle, gave him the real thing (1 unit) @ apx 9:45am. He did well with the shot and didn't seem to notice but then hissed when the nurse when to weigh him. I have not heard him meow since we left the vet. He stayed under the neighbor's porch most of the day and didn't eat what was left for his lunch until this evening. I got home from work apx. 8:15pm he barely ate any dinner and immediately wanted outside. Again, he hasn't meowed at all, just stood by the door. I have not given his evening dose of insulin because 1, he didn't eat his dinner and 2, he's currently back under the neighbor's porch refusing to come when I call. I will mention, it was very hot out today. It's also about to storm and it just doesn't seem normal for him to want to be out like this. I'm sorry if I sound ridiculous, but I'm absolutely terrified that something is wrong. Any advice is welcome! Thank you in advance!!
