We discovered how much my last tux cat loved watermelon when we cut one in half, got distracted by I don’t know it’s not important, came back in half an hour and she was standing in the watermelon devouring it. She had eaten half while my back was turned. I’m not even sure I can eat that much watermelon that fast, it was a big melon and she went down to the green. I stop at the white. We made sure to buy her a new melon every week while they were in season, but we kept her to much more reasonable portions.
