tricollie,

yeah I understand what you're saying. my counter cat, zephyra was just like bonnie when I first got her. and since she was my first and only one I had, I free feed because she wouldn't take more than 10 bites. ...until I got ocean and miles...boys eat all they want!!! then I've stopped free feed and fed three (oh my gosh..only three...lol) 1/3 cup 2x/day.

and pour out the amount would fit her "10 bites" (leaves 2/3 nibbles). so the food can be gone before the boys get hers. but every three days, I put more in zephyra to see if she have increased her "bites", she did! by doing it so again until she has reached her limit. and setting time, limited to her bowl, she seems to get hungier but full at a perfect time (well, two or one nibble left) - heh.

you said bonnie would eat half, maybe just put half in it. and she'll live by a few hours getting another half or even a cup! I do feel guilty by taking away their 'unfinished' dishes but not like you would leave your two-legged kids' food out there! ..(eww). training time, kids!
