Hubby & I get paid Bi-weekly but our budget is based on a weekly system.

$90 per week/$360 per month for the regular grocery stores and also an additional $10 per week/$40 per month for Sam's Club which we go to once every 3-4 months. With that money we buy not only our food, but toilet paper, cleaners, laundry products, and any eating out we may do which is about once a month and our horrible soda pop addiction.

The cats have a separate budget of $32 per week/$130 per month. Most of the time that covers the food and general vet visits (I get a big discount by working at the hospital) we do go overbudget if any of the cats gets sick and requires more vet care or I find a sale on litter because I can't get that from work I have to get from the pet store and I usually buy like 100lbs at a time .
