I have been leaving it down quite a long while. She has amazing willpower, apparently.
She does eat a bit, here & there, and isn't dehydrated or avoiding her litter box.
Maybe she just isn't eating as much because she's in a non-growth spurt period?
I don't think it's the heat - we have a/c and she's always inside.
Thanks for replying Badger, you're probably right, nothing to worry about.
My 10 year old thinks it's because I've spoiled her with variety and now she wants different food for every snack. Who knows, he may be right!!!
