New here- Confused about feeding schedule

Member Since 2025
Hi, My Simon, age 15, is newly diagnosed (3 days). My vet says ONLY feed 15-30 mins before injection, twice a day. He won’t eat enough at that point in time for a full 12 hours. He begs all day for food. Some of my reading suggests 3-4 small meals thru the day. What should I do? I do have 2 other younger cats also frustrated by the change in feeding schedule, which had been 4x/day.
 
What insulin are you using? It depends on the insulin, The best insulin for cats are ProZinc and Lantus they are a 12-hour insulin easy on the cat, unlike some vets that recommend to feed twice a day, that is incorrect a diabetic cat needs to have two main meals a day plus 3-4 small meals or snacks during the day to keep the insulin in check, home testing is very important you want to test before each shot, to avoid hypoglycemia, just like humans with diabetes, they eat several meals during the day for the same reason and at least tests 2-3 times during the day, most members including myself use the ReliOn Premier human monitor and strips, inexpensive and accurate, we mostly base our numbers on human monitors, no need for a Pet monitor a diabetic cat cannot digest carbs, so is important that their diet consist of wet can food or raw between 0-10% carbs, most members feed up to 5% carbs, if you let us where are you can send a food list from you Country as well, we are here for you we have members that update their knowledge on diabetes daily, we can help you with dosing as well and any concern you may have😉
 
If you have other cats like me, I made the transition slowly, since both grew up on MEAUMIX dry food, so is good they all have the same schedule and food and keeping an eye of your diabetic cat as you don’t want him gorging on food either

I am using prozinc. We are trying to test but are still not getting enough blood. Will give snacks and try to test again soon. We did feed a mix of wet and dry so are transitioning to all wet - a low carb food already, fortunately. THANK you!
 
It is absolutely fine to feed more than twice a day. Several smaller meals are easier on your cat's hopefully healing pancreas. The notion of feeding only twice a day is based on shorter acting insulin than either Prozinc or Lantus which are the insulins recommended for treating feline diabetes. With the shorter acting insulin, they act much more quickly so it's critical to have food on board before you give a shot. That's not the case with Prozinc. Given that shorter acting insulin doesn't last for the full 12-hour cycle, it's less important to give several small meals. Prozinc had a long duration. We typically suggest several small portions up until nadir (the lowest point in the cycle) and making sure to not give any food in the 2 hours prior to the next dose of insulin.
 
So with prozinc and canned food, I’m thinking a good long term plan will be 6 am feed, 6:30 injection, snack about 10, lunch a half can at noon, snack about 3, full can at 6 pm, 6:30 evening injection, and another half-can around 11-midnight before bed. Does that sound appropriate? Snacks would be dried chicken most likely, and right now we are feeding purina pro plan urinary formula. We have another cat who requires it.
 
it is not necessary to wait, the protocol for ProZinc is test, feed shoot you an shoot while your cat is eating, just get behind him pick up the scruff and shoot, if you want to get an idea how to feed click on Corky's spreadsheet in blue below, scroll to the left you can see his daily menu and amount and times he is fed, and get an idea you are doing a great job, we are very numbers oriented, we would like you to create a spreadsheet, this way we can help you better by seeing the daily development Simon is reacting with the insulin and we an also assist you with dosing if necessary

The urinary dry food may not be needed at all, despite what the vet says. Give this a read: Cat Urinary Tract Diseases: Cystitis, Urethral Obstruction, Urinary Tract Infection

Increasing water intake helps in most cases. This is easily done by feeding only canned food, extra water added if the cat likes that. A supplement such as d-mannose can help with some types of urinary issues.

A microchip feeder can keep the diabetic cat out of the food the other cats eats. But feeding all the cats the same low carb canned food only diet is easiest.
 
You are all relieving me considerably. We got a single bood sample from Simon this afternoon at about 4:20. He was at 91 so I felt good about that, even if is unlikely tobethenadir reading. We will try earlier tomorrow now that we have a procedure, and will start keeping a log.

Feed him a small meal at +2 and +4 and if you need to at +6. What was your previous feeding schedule? Maybe you don’t need to change much at all. I just don’t recommend feeding much after nadir (lowest point in the cycle) because it can sometimes cause the BG numbers to rise prematurely.

How much insulin is he getting? How many hours after his shot was that? (The 91?)

As soon as you get your spreadsheet set up, please post over on the ProZinc forum so that I can help with your dosing.

It was about 10 hours after his shot. He is getting 1 unit right now. We go back Monday for a single blood test, then on Friday for a full curve. Tomorrow I hope we can test several times ourselves and get a better idea of the day’s pattern. He seems very much more normal in his behavior today, unlike the previous 4-5 days.

Previously we had fed canned at 6am and 6pm, with kibble at 10 am and 10 pm. We have stopped letting Simon have kibble (replacing with half a can), and will be weaning the other two way back or off entirely. Simon never ate much of it, anyway. We intend to dose at 6am and 6 pm or shortly after from now on.

Okay so of he was at 91 at +10 (ten hours after his shot) it is quite likely that his nador was lower than we want it to be. His nadir was probably somewhere between +4 and +6. Can you get a fasting preshot test tomorrow and then a +4 and a +6 (or just a +6 if it’s really a problem and you’re just not good at it yet.)

I will try! I am alone at the 6 am (if you don’t count my elderly mom), so that one may be hard, but the +4 and +6 should be doable, as hubby will be up and around then.

Okay. So it’s very good to give a small amount of canned food at +2 and +4. The +2 snack is important because ProZinc onsets (starts lowering BG) at about +2 for most cats. Then another small amount of LC canned food again at +4 is good if you can do it. A tablespoon or two of LC wet food will be fine. These mini meals help smooth the cycles and prevent steep drops in blood glucose (BG.)

If you can get up to speed on home testing then you won’t need to take him to the vet for curves anymore.

Understood. The preshot tests are important because you need to know that he’s not too low to give the full dose or whether you should shoot a reduced dose or maybe even skip the dose. But it’s very new for you now so I understand it’s a challenge!
