Ishould have googled first..lol

Just found this on their website...

Can I freeze your product?
As the food is 100% natural and there are no additives it is fine to freeze and then later defrost the products after they have been packed in an airtight container. Please ensure that you exclude as much air as possible to prevent freezer burn. Defrost ONLY in your refrigerator or microwave and consume this product immediately after it is defrosted. Although this product can be frozen, Rafferty’s must emphasise that as this is a fresh, natural product; that is best served from the packet or within 48 hours from opening.
So I guess I can freeze it in icecube trays then just put the cubes in a ziplock bag like i do for her other food.

Thanks for your replies Salad & Starrysky
