Double check your condo date, Shirley. It says 3/3 instead of 3/31.
Regarding the autofeeders:
Yes you can leave canned food in them. Some people, me included, use the Cat Mate C500 and it has ice packs underneath. Others use the Petsafe 5. I'm not sure whether it has ice packs or not. But you can also freeze the later portions of Haley's meals and they will thaw out by the time the compartments open.
