Can openers (Wal-mart, problem)

[harry chickpea]

Anyone else having problems with opening cans recently? Every time I try to open the new five ounce cans of tuna from Walmart, the standard can opener slips and can't get traction, and the other style of can opener that removes the lid won't cut properly. Regular cans of vegetables and soups don't seem to be a problem.

I have cats and open wal-mart tuna everyday ;no probelm with my opener.If its a manual they wear out and cat like that becuase the blade gets dull. Some cans are harder to open.
