While it's ok to put our products in the refrigerator, especially in hot climates, Health Extension does not recommend freezing kibble since there are probiotics sprayed onto the food after cooking and the nutritional values of the product cannot be guaranteed upon defrosting. Also, freezing canned products, treats or toppers is not recommended, since the nutritional values of the product cannot be guaranteed upon defrosting as well. These items are not designed to withstand the low temperatures of a freezer.
