Hi, I posted an introduction on this forum last year regarding my cat, Mommy. I know I've been absent since then. This isn't an easy post for me to write, but I'm hoping for some helpful advice and forgiveness for my ignorance. Per my last post: Because everyone, my idiot ex-vet included, seemed unsure as to whether our Mommy Cat was diabetic or not, we made the preventive measure of switching her and our other cat Boy to a low carb wet food exclusively last year (Friskies Classic Pate). She did fine on it, and continued acting normally. She never developed the excessive urination or drinking often associated with diabetes, as I kept a close eye on that. Nor was her appetite more increased than usual. Last month, however, we went on an extended vacation (two and 1/2 weeks) and employed our usual cat sitter. No issues with the sitter, as my two former ferals don't let anyone but us near them, yet once we returned home, we noticed Mommy was looking very frail and underweight - as in, extremely bony around her hips and spine, a marked shift in her. Her gait also seemed impaired. She's moving slowly, not on her hocks, but as if she's in pain, like arthritis. I thought maybe she'd been eating less due to our absence, though the sitter assured me she'd been eating, based on the empty plates, so I upped her feeding to four times daily; I'm a novelist and work at home, so that's easy to do. Mommy kept eating, but gained no weight. She also gradually became more lethargic throughout November, which was hard to quantify at first as she's always been a sedate cat who stays upstairs in her Princess Suite (the extra bedroom) and she tends to sleeps most of the day as a rule. Last week, however, her lethargy turned pronounced and her appetite waned considerably, so I called the vet. I became furious when the vet again requested that I home-test her urine for glucose "to be sure", because really, at this point, based on her initial blood-work and her current state, it seems clear to me that she must be diabetic and uncontrolled, at that. I searched for another vet in a panic and found one that only treats cats; we go in today at 3:30 pm. Getting ASAP appointments at vets these days in San Francisco is a nightmare, they're all booked out weeks in advance. I also enticed her appetite with tuna; she resumed eating some of her wet food with added tuna sprinkles for a while, but yesterday only a little and today not at all. She's still joining us in bed at night and comes out when we call her, she purrs and wants affection, but she's obviously not feeling well at all. And she's gotten so very thin, even her fur looks depleted. She's a ghost of the cat she was. In any event, I've been reading this forum diligently, all the stickies and info I can absorb. I know that with some practice and patience, I can home-test her glucose levels and do insulin shots, as well as needed curves. My questions are: If she's been an untreated diabetic for nearly two years, as now seems to be the case, is there any hope we can get her stabilized? I don't expect remission at this point, I'm aware that window may well be closed, but I'd like to try to save her and provide her with a few more years of quality life. She's a senior cat, but probably not yet in her mid-teens, maybe 12 or 13 at the most. Most likely, she's 11 or 12, based on when I first found / trapped her in the park, had her spayed, and the length of time she's lived at home with us and her son, Boy, which would be 7 years now. Also, is Lentus the preferred insulin to start? I realize it all depends on the cat and their response, but from all my reading, Lentus appears to be the least "harsh" initiation insulin. She may well require hospitalization today, I'm worried she might have ketatones, which would explain what looks like nausea to me when she approaches the food dish, so I'm trying to take this one step at a time. I broke down yesterday, crying like a child. I adore my cats, I rescued them, and have always been proactive in my pet care. I should never have heeded my ex-vet's "wait and see" approach. I feel guilty that my ignorance and lack of incentive aggravated Mommy's condition, though I also realize other pet owners must face this dilemma. It all felt so overwhelming at first that I seized on the diet change as the one thing I could control. Which was stupid of me, in hindsight. I hope we might be able to save her.
