I only have one kitty, so I'm not sure my input will be worth anything, but...

FOOD: Pinot only gets a little over 1/2c daily of Science Diet indoor dry. 1/4 in the morning in water, and 1/4 in the evening with a forkful of Science Diet canned in evening meal only (small cans, each can lasts 4 meals), mixed in water. So, she goes through about two small cans a week; the dry lasts a long time.

TREATS: She only gets, at most, 5-6 treats a day. They also last a long time. She only eats the Whisker Lickins crunchy tartar control.

TOYS: We have had Pinot for just over a year and a half; the toy graveyard is-one fishy (resewn several times, finally had to go), countless busy balls, lots of lost hair ties. She has MANY toys.

LITTER: We were buying the 30lb bags (Tidy Cat regular non-clumping), but found WalMart has the small bags at the same price. They're a few pounds each, and one bag is one litter change-a lot more convenient! Her box is changed out completely every 4 days.
