I posted some info on Tashie's condo about feeding lower numbers and maybe it would also help you.
The other day, we fed Tashie HC at 54 @+3.5. Usually we say, feed LC unless they are below 50. But....there are exceptions:
•a fast drop to a lower number
•a new kitty with little data and a nervous caregiver
•a low number really early in the cycle
Take a look at Gabbys SS. Gabby generally has an early nadir and likes to drop early and fast. You can see how Sienne uses HC with her to slow her down.
The goal in a newly dx cat (dx less than one year) is NOT to prevent a reduction; it's to keep them safe and try to minimize the bounce that comes with a really fast and steep drop.
If you get a 54 midcycle from a glide down, you would use LC food. You will also learn what Tashie reacts to best. For instance, I used alot of HC gravy, food, karo when Gracie was newly dx and on Lantus. But then I figured out she responded really great to 10% food. I never use HC or gravy and restrict the use of karo to really really low numbers (20s/low 30s) when I want her up fast. ECID...learn what Tashie responds to and use what she needs.
If you get a 54 late cycle, you might not need to feed OR a tiny bit (1 tsp) of LC might work beautifully. So consider:
1. How fast is she dropping
2. Where is the number in the cycle
3. How does she respond
And lastly....feed the 40s. If you get a 40s number at PS, do not feed, retest in 15 mins. If she is not above 50, feed 1 small tsp LC and retest in 20 mins. In the meantime, you will be posting and asking for help
I think managing any curve with food becomes an art. The tricky part is learning how your cat responds to food. As you feel more comfortable with low numbers, then you can develop a "chart" like Dyana has. She knows JD well and knows when to feed what. We also have figured out the same with Gracie and Sienne has with Gabby. It just takes time and patience to see how they respond and to learn what they need.
