That would be a violation of animal rights. Someone just put a cat in the mailbox and took a picture.
Because a cactus is covered in spikes, it would be extremely uncomfortable for this cat were it to try to eat it. Besides, cats do not like to eat plants. They like fish.
In fact, unless it makes noise, looks like fun, tastes good or is comfortable to lay on your cat probably has no interest in it at all.
Cats do not have any musical ability or comprehension. They cannot read music. They don’t even have thumbs.
