Yes.
If you manage the curve with food by feeding their regular LC food at specific times, it can slow down those drops....usually. For instance, for a lantus kitty, you might try taking his regular portion of food he gets each cycle and dividing it into four mini meals fed at PS, +1, +2, +3. You might have to experiment a little bit. When Gracie was on lantus, I found that I needed to give her the larger portions at PS and +1 and smaller ones at +2 and +3. The goal is to get them to surf a little higher but in nice, healing, normal numbers instead of drop like a rocket to a reduction that they won't hold.
