Place 2 days worth of food in the refrigerator right away so you can begin 2 days after that. Then simply move 2 days worth of food to the refrigerator every other day so you always have a thawed portion that’s ready to feed. For optimal freshness and safety, your refrigerator should be 40º or below and thawed raw meat should be consumed within 3 - 4 days.
Most dogs will readily eat refrigerator temperature food. If anything is not eaten after 45 minutes, put it back in the refrigerator for later. Some dogs will throw up if they eat it too fast and it's too cold. You may want to allow it to warm up a bit to room temperature or you can add some hot water to take some of the chill out.
Raw meaty bones (RMBs) are fine to feed at refrigerator temperature. They usually take a bit longer to eat so they will warm up as your dog is chewing on them. Dogs may be hesitant at first with raw meaty bones if they haven’t ever eaten them before. Your dog may sniff at it for a while and not know quite what to do. Eating them slowly is fine. If possible, it's best to feed RMBs outside. They can be messy and dogs sometimes like to try to take them somewhere else in the house. Like your couch ; )
For cats, if you're transitioning them to raw food, it can take a little bit of time for them to get used to it. Some cats and most kittens will eat it right away without any hesitation. If they're eating dry kibble now, you may need to switch them to wet food first. Then you can mix the raw in with the wet and keep increasing the percentage of raw until it's all raw. Cats tend to prefer it room temperature and may wait until it’s warmed up a bit to eat it. It can take a few weeks and a lot of patience.
