Question about Royal Canin glycobalance

Hey everyone! Hope all is well

So I just talked on the phone with the vet I plan on using for Onyx and they asked how much I'm feeding him and I told them I'm feeding him two cans twice a day and they said that's too much and I should only be feeding him one can per meal. But his old vet told us to feed him two. The cans are only 3 ounces and I don't want him to go hungry or have his blood sugar be too low. Does anyone else use this food? If so, how much do you feed your cat?

Also I was told that royal canin glycobalance was high in carbs. So is it even safe for him?

Sorry for the questions. I just keep getting different answers from these vets.

 

The Glycobalance wet food is 14% carbs: http://catinfo.org/chart/index.php

The manufacturer's feeding guidelines can be seen here: https://www.royalcanin.com/products...od-3-oz-morsels-in-gravy-24-cans-case-/429203
There is a chart based on weight:

Weight Daily Feeding
4.4 lb (2 kg) 1 7/8 cans (164 g)
6.6 lb (3 kg) 2 5/8 cans (218 g)
8.8 lb (4 kg) 3 1/8 cans (268 g)
11.0 lb (5 kg) 3 3/4 cans (314 g)
13.2 lb (6 kg) 4 1/4 cans (357 g)
15.4 lb (7 kg) 4 3/4 cans (399 g)
17.6 lb (8 kg) 5 1/8 cans (439 g)
19.8 lb (9 kg) 5 5/8 cans (477 g)
22.0 lb (10 kg) 6 cans (514 g)

 

It's higher in carbs than we'd like...we recommend feeding foods that are less than 10% carbs.

There's nothing special in those "diabetic" foods (other than the price) Most of us feed Fancy Feast Classics, Friskies pates or 9-Lives ground because they're not only low carb, but affordable and easy to find!

The "recommendations" on foods are almost always over-inflated. The best thing you can do is to weigh your cat once a week and then adjust the amount of food they're eating accordingly
