...as I just picked up another Monster Bag of Royal Canin SO dry food at my vet's.

Price when I bought it June 12/06: CDN 46.78 plus tax of 3.27
USD 42.31 plus tax of 2.96

Weight: 7.5 kg/16.534 lbs

Days lasted: 95

Price including tax divided by 95: CDN $ .53 per day (two cats)
USD $ .48 per day (two cats)

Times by 30, for reasons I will note below: CDN $15.90/US $14.40

To treat Oscar's bladder infection, and a few crystals, cost me just short of $400 (CDN ) over one month (30 days).

Hope this helps anyone who is trying to figure this out!

PS: The SO wet food, they get just once a day as a treat. I got the wet on the same day, and there's enough to get almost to the end of the month. It totals $31.17 (new price). Even at 95 days, it's $ .38 per day.

The Dry food went up in price to a total of $52.21. So that is $ .55 per day.

Okay, gotta stop. This is making my head hurt....
