Playing with and Training Your Mice

Mice are often underestimated as pets, but they are remarkably intelligent, curious, and trainable animals. In the wild, mice explore large territories, construct complex nests, and forage constantly. In captivity, providing adequate enrichment is essential — a bored mouse will bar-chew, over-groom, and may develop stress-related health problems.¹

Female mice in particular are highly social and thrive in groups of two or more. Male mice are generally housed alone to prevent fighting, but they still need rich enrichment to compensate for the lack of social interaction. See our Introductions & Bonding article for guidance on housing mice together.

The Wheel

A solid-surface wheel is important enrichment for mice. The wheel should be at least 15–17 cm (6–7 inches) in diameter for adult mice, with a solid running surface. Mice will use their wheel extensively at night.²

Enrichment Ideas

Enrichment Type	Ideas
Climbing	Branches, rope ladders, multi-level platforms
Nesting	Tissue paper, hay, coconut fiber — mice love to build elaborate nests
Foraging	Scatter seeds in bedding, hide treats in cardboard tubes
Chewing	Cardboard, wooden blocks, cork bark
Tunneling	Cardboard tubes, commercial tunnels, PVC pipe sections
Digging	Deep substrate layer (at least 10 cm / 4 inches)

Mice are highly motivated by food and will spend hours foraging if their food is scattered rather than placed in a bowl. This is one of the simplest and most effective enrichment strategies available.³

Training Your Mice

Mice are surprisingly trainable and can learn a variety of behaviors through positive reinforcement. Sessions should be very short (3–5 minutes) and conducted when mice are naturally active (evening).

Target training:

1. Offer a tiny piece of treat (a sunflower seed, a small piece of cheese, or a grain of puffed rice) on the tip of your finger or a target stick.
2. When the mouse sniffs or touches it, reward immediately.
3. Move the target progressively further away so they have to walk toward it.
4. Use the target to guide them through tunnels, onto your hand, or around an obstacle course.

Maze and puzzle training: Mice excel at maze learning and will quickly learn to navigate a maze for a food reward. You can build simple mazes from cardboard boxes and tubes. Changing the maze layout regularly keeps the challenge fresh.⁴

Tricks mice can learn:

• Spin in a circle
• Stand up on hind legs
• Jump through a small hoop
• Come when called (name + treat pairing)
