They're so sneaky like that - and that's when it usually happens - mid to late cycle...glad to see you're getting more tests.
Congrats on the reducie. Do you have medium carb food on hand to slow him down when he appears to be dropping? You want to try to keep him from dropping too fast or going so low if possible.
Oh, that was sneaky. I was thinking he may need an increase.It may be good to note on the SS that it took 7 cycles from last greens to last night's lime greens. Some cats take up to 10 cycles to break a bounce.
