Lisa Murray-Lang, 44, used cardboard boxes and dolls furniture to recreate iconic scenes for her Syrian hamster, Spud, to explore.
She hand-crafted every element - including tiny bar stools and hamster-themed artwork on the walls.
Lisa - a former graphic designer - tweaked the logos - turning the pub from Coronation Street into the 'Rodent's Return' and Hogwarts into 'Hamwarts'.
It took Lisa between up to three days to complete each sets and Spud's adventures have also taken him to 10 Downing Street and the National Gallery.
Lisa, a professional dog walker, has had to temporarily stop working and turned to model-making to pass the time.
Lisa, from Birmingham, West Midlands, said: "Spud loves it - he's always excited for his next adventure.
"Every time I get him out and it's just to go in his ball now he's disappointed.
"Finding miniature dolls furniture online has opened up a whole new world.
"I found him a tiny pair of gold glasses so Spud could look like Harry Potter.
"It's a bit of fun and it gives me something to focus on."
Lisa got Spud, who she named after the character in Trainspotting, in June 2019.
She started making the tiny scenes in March when the UK went into lockdown.
Lisa was first inspired by a similar video of guinea pigs running around a miniature scene.
She said: "My job as a pet sitter and dog walker came to a grinding halt during lockdown.
"I needed a way to stay busy and then my friend sent me a video of guinea pigs in a tiny art gallery.
"I thought: 'That's it, Spud has to go too!' "And I got to work making my own version."
Lisa lives at home with her husband William Lang, 63, and their four cats.
She's hoping to turn Spud's adventures into childrens 'books one day and has launched a crowdfunding page to pay for it.
She said: "Looking at me, you might think I'm mad, but it's a bit of fun.”
