Some cat owners report their cats eat strawberries and are ok, however it is rare that cats are not effected by them.
Most cats will not eat strawberries, even if you give it to them, because they do not like the sweet taste of them.
Cats should not eat a lot of fruits. Strawberries, and other fruits have an acidic effect, and should not be given directly to cats.
Some foods will include small portions of strawberry. In very small pinch size amounts, a cats system can handle strawberry, but it should not be given in large amounts.
If your cat has already eaten a strawberry, you don’t need to worry too much. Watch your cat to make sure it does not have any immediate side effects. If you notice your cat acting strange take it to the vet. Otherwise, just try your best not to let your cat eat any more.
As this video shows, some cats are ok with eating them. Just because this video shows a cat eating one, do not feed your cat a strawberry like this.
