Is it safe to buy cat dry food from an opened sack or sealed bag?

That's a good question. If the paint was all nice and dry, it should be fine. It's good to keep food in an airtight container, even better if you put the original bag itself in an airtight container. This prevents oxidation. I'm not sure where paint buckets fall on the airtight scale. It's likely safe, but if you don't need to use it, I'd probably avoid it just in case.

The safest option is to discard it. There may be bacterial or fungal growth in old food since it has been open and exposed to air and light. Nutritional value is likely decreased as well. https://www.petcoach.co/article/how-to-safely-store-pet-food

Great question! I always keep my dog food in an airtight plastic container. It helps keep it fresh, and the container also prevents any other creatures from getting the food such as insects. I recommend a container. I hope this helps :-)

Hi there! Dry food isn't a concern with being left out, it's the wet food that's a problem. In the heat, that can certainly go bad quicker than it would in the summer. It's absolutely fine to put the leftover food back into the dry food container. I leave food out for my cats all the time, I use a self feeder and I haven't had any problems with the food rotting whether it's summer or winter :-)

No, I would not recommend you feed that food. You could contact where you bought the bag of food or the manufacturer to enquire wether it is normal for a bag of food being breached by mouse. Hope this helps, thank you for using Petco Pet Education Center, formerly Petcoach !

The procedure of freeze drying is safe, but not necessary or any better for a cat food. My first question would be whether it's nutritionally adequate. In order for a food to be nutritionally adequate it must have gone through a diet trial, or was formulated based on know nutritional requirements. In order to find this out, you will have to research the food a little more. Different countries will have different or no requirements for the company to show that the food is nutritionally adequate. For more information about choosing a food, I recommend you read the short article at the link below. https://www.petcoach.co/article/what-to-look-for-when-choosing-your-pet-s-food/ I hope that helps and all is well.

Dry commercial dog foods are shelf stable and do not require refrigeration or freezing for storage. Store any open food in a food-grade container that seals well at room temperature. Be sure to use all food before the expiration date printed on the bag.
