My cat surprises me. He is a pet, but still he is a predator, eats meat, has to catch mice, fight other cats, and instead he tries to eat our grapes. It was interesting to watch how he was trying to get the berries, he walked in a circle, saw the berries, but did not understand how to get them, at some point it dawned on him that he had to open the lid, but there was a problem, the glass lid was heavy and not lifting . Of course we treated him with a berry, it turned out for him the berry is a ball, which he then drove around the apartment all day like a kitten!
