After treats are done baking leave them in oven, after U turn oven off, crack door for a minute or then close door and let them stay in there while oven cools. It will dry them out so U won’t need to refrigerate them. Or dehydrate them when done baking.

The baked treats should be able to be stored at room temperature but they won’t last as long as they would in the fridge.

I don’t know if they are safe for cats or not. I did find that cats can have the plain meat baby food but not the fruits or vegetables. I was unable to find out if they can have oatmeal baby food. I would assume these are not safe for cats. I only have dog treat recipes as my cat is super picky in what she eats.
