Very cute! In Austin there is a guy that walks the streets with a big dog and on that dog is a cat and on the cat is a rat. When I find photo I will post it.
My sister once had tiny "furhamsters" (I don't know if they are called that in English, they were the size of mice, but very furry). At that time Pollýanna and I lived at my parents for a while. When we let the hamsters run free, or let them close to Pollýanna, she would run away, very afraid of those moving creatures!
