Let's rhyme

Laara was a lady of fat, Lived in a lovely flat, She paid the valuable vat, And over taxed by that, I met her on Monday to chat , I went with the head hat, And I liked her pet pat, What did I look at? I saw a small rat, And it was chased by a cat, which bounced on the below mat, Dropped it's small scat, I tried to beat with the bat, But it escaped like the best brat, And glided as a tiny gnat, I went near her sofa and sat, And caught by her catchy tat.
