Your cat tries to hide his food and you are trying to figure out why.
I have never seen this behavior in my cats but it does happen. You might see your cat or kitten paw at the ground near the food bowl, usually, after he has eaten. This would be an instinctive desire to bury or hide the food to protect it from other predators; a hard-wired instinct inherited from the domestic cat’s wildcat ancestor. Your cat is trying to drag earth or leaves over the food bowl.
To some cat caretakers it can give the impression that their cat does not like the food and is trying to bury it to get rid of it. This is not the case.
One wild cat species that is well know for this behavior is the cougar (mountain lion or puma). This cat buries prey under leaves, snow or other available movable objects. I can remember a story of a person who slept outside and woke up to find himself buried under a pile of leaves. A cougar had treated him as a potential meal and buried him while he slept with the intention of coming back for breakfast! He woke up first. Note: cougars don’t eat people.
A kitten or cat might make an attempt to bury food even if he is a full-time indoor cat. It makes no difference whether there is any chance of a predator stealing the food or if the food is regularly supplied by the owner.
That said, I wonder if this behavior is more likely to occur in households where there may be competition for the food from several cats. It may also happen more often when a cat is stressed or insecure but that is a guess.
Apparently cats have been known to drag an object, such as a towel, over the food to hide it. A variation on this is for a domestic cat to bring an object that he has played with back to the food or water bowl and drop it in or nearby. The toy is prey and the cat is bringing prey back to his den or secure place. The nearest a domestic cat gets to this is the position of his food and water. In the picture there are lots of toys in and around the food. This can looks as if he is trying to hide the food. The cat’s caretaker believed he was trying to bury it because he did not like it.
Personally, I have not seen this behavior either. It is individualistic cat behavior. I would expect it to be quite unusual. A similar form of cat behavior is pawing at water or shiny surfaces.
