Meet the mice
Every painting begins with a character, a little drama and the light that brings the moment to life.
The last jelly baby
Rocky
The blue tit from Jelly Belly has joined the feast, but neither bird nor mouse is willing to give up the last jelly baby. A tiny tug-of-war begins.
Exercise time
Catch Me If You Can!
Poppy has spotted her favourite thing—a tennis ball—and she’s off! One determined mouse races ahead with it, while another clings to Poppy’s flying tail. A two-panel chase full of energy and mischief.
A little moment of friendship
Carrier Pigeon
A generous little mouse offers a morsel to a splendid pigeon, while a friend enjoys the view from up on its back.
A very tasty hiding place
Shush
Two SuMmice have found a delicious hiding place inside a towering burger. One sits under the lettuce; the other sits on top of the tomato, surrounded by dripping cheese. It looks like the perfect place to hide—if only they can keep quiet!
A seaside escape
I Do Like to Be Beside the Seaside!
Two little mice make a daring escape from a giant burger by the seaside. One carries a precious egg while the other rolls a tomato away. But a hungry gull is swooping in—can the pair make it to safety?
Disclaimer: No creatures were harmed in the painting of this SuMmiceterpiece! 😉🐭🐦⬛
One more turn
Again, Again
The little mouse asks for one more ride. Mum is tired, but she winds the key one more time. She knows these days won’t last forever: soon her little one will grow up, and the carousel may no longer hold the same magic.
A very generous afternoon tea
Bottoms Up!
We all love an afternoon tea, some more than others! These SuMmice have found a feast of sandwiches, cakes and pastries—and they’re making the most of every tier.
Notes from the studio
The little stories
News, ideas and behind-the-scenes moments from Susan’s painting table.
A little handmade treasure
Bonnie on a whiskey bottle
I had an old whiskey bottle and decided to paint little Bonnie on it using glass paints. I baked it in the oven, and it worked really well!
A little experiment that turned an old bottle into something special.
A welcome
Welcome to my little world of big stories
Hello, I’m Susan, the artist behind SuMmice. I paint original oil paintings filled with tiny mice and the animals, objects and adventures they meet along the way.
Each SuMmiceterpiece starts with a story. It might be a small moment of friendship, a mischievous escape or a funny idea that makes me smile. I love bringing those moments to life with expressive characters, little details and dramatic light.
This blog is where I’ll share new paintings, the stories behind them and a few glimpses of life in the studio. I’m glad you’re here.
Thank you for stepping into their world. — Susan x
The artist behind the mice
Painted with a little mischief.
I’m Susan, the painter behind SuMmice. I love building a story from small details: the tilt of a head, a bright eye, a patch of warm light against the dark.
My mice and their animal friends have become familiar characters to me. Each painting is a new little adventure for them — and I hope it brings a smile to you, too.
