cat food

i put my cat's food in the fridge but the cover came off and i did not realise it,it was in the fridge just not covered is it okay?

How long was it in the fridge? It should be fine, really, unless it's been there for several days. You can try and take a whiff of it to see if the smell has changed or absorbed whatever else was in the fridge, but cat noses are pretty fine tuned too. If it smells off, they may not want to eat it.
