Do friends know that cat food is bought in winter and packed in self-sealed bags? Now that the weather is getting warmer and warmer, will this freezing be broken?

If it is sealed, it can be stored in a cool and dry place for a long time. If it is not sealed, it will expand with heat and contract with cold, especially cat food, which is really difficult to preserve. You can judge whether it swells when you just bought it and whether the taste has changed.
