So, once upon a time my family had a pet golden hamster called Harriet.
She loved to climb and play and run in her wheel... but she also liked to escape. At least two times, she sent us into fits of worry as we searched the flat for her, once finding her in the cupboard under the sink, feasting on a sponge, and another time behind the bookcase (we coaxed her out with a biscuit).
I think about her often. She lived quite long life for a hamster, and died peacefully in her sleep.
Here's a little tribute to her :)
