Unfortunately, SLGS allows for increases only once a week. It also requires that you hold a failed reduction a week and take back-to-back reductions even though they are likely to fail. It was written for caregivers who can just about manage to get pre-shot tests, so it is very conservative. There are a few people who test enough for TR but have to follow SLGS because they feed dry food. TR requires that a cat is fed a low carb canned food. It predates low carb dry food. Because dry food is a different animal from wet food, the belief is that one does not know how it affects numbers. So TR might be too aggressive for a cat on dry food since TR was studied and published for canned food.
With cats who have a history of ketones or DKA, some fast-tracking of dose is done with SLGS when the members test enough for TR. We also recommend that members who test often work with a lower reduction point and try and avoid back-to-back reductions by preventing drops below the reduction point.
In Sly's case, let's see what he does on 5.5 in the next 2-3 days. Maybe that is all he needs for now. Paws crossed.
