That doesn't make any sense. Why would cat food be any different from any other food in the refrigerator?
Now if you open the refrigerator and roaches pour out of it, then that is a problem that the cat food could be contributing to. But if the cans are sealed or bagged and the roaches cannot get inside, I don't see where it could be a problem.
Why not put the cans inside of a zip lock bag, or get a rubber lid seal and keep it closed.
All food should be sealed anyway, even inside the refrigerator. As long as there are no strong food odors, the cans are sealed, etc, I would look elsewhere such as overall sanitation for the cause of the roach problem.
Hope this helps.
