As you can see corns contain a lot of carbohydrates, fat, acidic content, water, and phosphorus, a hint of salt, a little calcium

Unfortunately, cats cannot eat acorns at all. Because of the sheer amount of acidic content, water, carbs, and phosphorus content that they contain, if they are ingested by your kitty they can cause them to have diarrhea or be sick.

If they are going to eat any acorns then they are likely to only eat one at most so it won’t do much damage. But eating more than that will result in your kitty suffering a more detrimental effect on their health.

There is also the risk of choking and the acorn splintering off in the throats as they try to chew it causing damage to their insides. If you do find that they have eaten a lot of them then it would be a good idea to consult your veterinary surgeon to check up on them.

If they have shown a deterioration of health then this should be an urgent priority. For the most part though they will not be interested in such foods. So when they are out and about they will tend to just ignore them as most of the time they just don’t appeal to their taste buds.

There is also the risk of them having bad bacteria on them from being outside and exposed to that which is bad for a cat.
