Just a word on "hypoglycemia"...
There is a difference between low numbers and hypoglycemia. Unless your cat is exhibiting symptoms of hypoglycemia (e.g., staggering, confusion, walking oddly, twitching, seizures, etc.), you're cat is in low numbers. A drop below 50 (on a human meter or 68 on a pet meter) is not hypoglycemia unless symptoms are present (i.e., a symptomatic hypoglycemic event). This drop in numbers represents low numbers. You don't want to leave your cat in low numbers because it can become hypoglycemia. This is why we refer to 50 or 68 depending on what kind of meter you're using as a "take action" number and why you reduce the dose.
