Canned pet food is more popular. If some cans cannot be eaten temporarily, they can be sealed first and sealed with a special canned lid.

Opened cans need to be sealed immediately, because most of the cans have a strong fishy smell. After opening, they are exposed to the environment, which not only easily breeds bacteria, attracts flies and other flying insects, but also emits a lot of fishy smell, resulting in odors in the kitchen and refrigerator. The basic steps of general canned preservation are to close the lid and seal it, and store it in a cool environment. The more common storage method is to directly press the can lid back to its original shape as much as possible, cover it on the box, pour the rest of the can into a plate, and then seal it with plastic wrap.

Another method is to put the pan over the can and then flip the whole upside down to seal the mouth of the can. If it's a soup can, just cover the can with a plate.
