I have notepads where I wrote that sentence. I didn't make the mistake of forgetting that the second animal is a dog. I did forgot to include an "s" in my sentence, though. Somewhat embarrassing when I realized I was writing a sentence to include all letters, but didn't include all letters.
I am still a fan of writing. More, drawing some diagrams, which I am terrible at. It really takes an intuitive sense of understanding space as you are drawing. All too often, I have drawn the boxes, without the space for names inside of them. It is frustrating.
