Do mice have bones?

Yes, mice have bones. No, mouse skeletons don’t “collapse.” Mice are just very small and effective home invaders. An average house mouse is between five and eight inches long and weighs only an ounce or less. A mouse’s skull is the biggest part of its body; if its head can fit through an opening, the rest of the body will fit as well. Unlike humans, mice have a sloping clavicle, or collarbone, which makings squeezing through small spaces easy.

The whiskers of a mouse can sense if there is enough space for the rest of the body to follow. That’s one reason mice always go nose first instead of backing up in reverse. Mice rely on their sense of touch and smell to navigate tricky spaces.

Can mice climb?

Yes, mice are excellent climbers and jumpers. As a matter of fact, mice can easily jump distances of two feet and climb up stairs, furniture, roughened walls and landscape features. What looks like a lovely trellis or climbing ivy to you looks like an invitation to a mouse. Pipes, wires and ropes are frequently used by mice as travel pathways.

Mice don’t seem to have a fear of heights and enjoy exploring the areas near their nest. They will climb in search of food, nesting materials, or to escape danger like a predator.

How small of a hole can a mouse fit through?

Keep that in mind and do an inspection of your home to find potential entry points. Gaps along the edges of doors, or openings for plumbing and utility lines offer an easy way in for a mouse. Inspecting the outside of your home at night, with all of the lights on inside may make it easier to notice small openings because you will see light shining through.

Mice also enter homes, buildings and other structures through the roof. Dryer vents, chimneys, and HVAC conduits can all provide easy access for rodents into your home. Block potential entry points with silicone caulk, steel wool, wire mesh or hardware cloth.

    • Hi Vanessa,
      I suspect the answer is yes. Mice have sharp nails on their paws that would probably shred the cling film. Keeping mice away from bird feed can be very challenging. If you haven’t already, make sure to store any food you’re not currently using in an airtight chew-proof container to prevent mice from getting it, and clean the area around the cage frequently. You can try using our botanical rodent repellent pouches in the area to make the mice stay away, but keep an eye on your bird for any changes in behavior since birds can be especially sensitive to essential oils.

  1. I’ve seen comments here and there that mice can jump about 2 feet with ease. My bed is probably about 2 1/2. Do you think they could jump onto my bed?

    Also. I think they like it in my closet. I’ve seen a mouse run in and out of the closet a few times.

    • Hi Carina,

      Mice are excellent jumpers and climbers, so it’s possible they would be able to get onto your bed even if it is about 2 1/2 feet above the floor. Closets are popular places for mice, since it’s an area you probably don’t spend much time in — it is easy for pests to hide there without being noticed.

      Try our 3 step plan to get rid of mice and stop them from coming back: 1) Clean up – Remove clutter mice might use to nest in such as piles of clothing, cardboard boxes, or seldom used items; 2) Seal up – look for any holes, cracks or gaps mice might use to get inside such along baseboards or electric outlets; 3) Pouch up – place pouches of EarthKind’s botanical rodent repellent in areas where you’ve seen mice activity. The scent from the pouches will repel mice for at least 30 days.
