How can you make a feeder for mice? - briefly
Construct a small, airtight container with a narrow entry slot and a sloped interior ramp that forces mice to push food upward as they feed. Secure the device to the cage wall or floor using clips or adhesive, and fill it with seed or pellet mix suitable for rodents.

How can you make a feeder for mice? - in detail
Designing a functional mouse feeder requires durability, ease of cleaning, and protection against spillage. Begin with material selection, then construct the main components, and finish with testing and maintenance guidelines.

Materials

Food‑grade plastic or stainless‑steel container (capacity 250–500 ml).
Small metal or plastic tube, inner diameter 8–10 mm, length 100–150 mm.
Two hinged lids with fine mesh (≈1 mm opening) to prevent escape.
Non‑toxic adhesive or silicone sealant.

Construction steps

Cut a circular opening in the container wall near the top; insert the tube so its lower end rests just above the container floor. Secure with sealant, ensuring a leak‑proof joint.
Attach the mesh lids to the container top and to the tube’s upper end, using hinges that allow opening for refilling and cleaning.
Drill a small vent hole (≈2 mm) on the side of the container to equalize pressure and discourage condensation.

Feeding mechanism

Load dry seed or pellet mixture into the container. Gravity will draw food down the tube, delivering a small amount each time a mouse pulls the mesh lid.
The narrow tube restricts the volume per access, limiting waste and keeping the environment tidy.

Testing and adjustments

Place the feeder in the cage, observe mouse interaction for 24 hours.
Verify that the mouse can open the mesh lid without excessive force; adjust hinge tension if necessary.
Ensure no food remains trapped in the tube; clean the interior after each refill.

Maintenance

Disassemble weekly; wash all components with warm water and mild detergent.
Rinse thoroughly and dry before reassembly to prevent mold growth.
Inspect seals and mesh for wear; replace any damaged parts promptly.

Following this procedure yields a reliable, hygienic feeding device that minimizes spillage and supports consistent nutrition for laboratory or pet mice.
