My cat gets a mix of dry and wet food.
When it comes to the wet food it's from those dinky little single meal cans...but at that size it is easy to examine the food carefully as it goes into her dish. I haven't come across any bits of metal or plastic or mould, and none of them have made her ill.
I haven't had any issues with the dry food either, but then again all her meals are at the middle to (mostly) high quality level food range and none are made by Mars.
