How to Make Hamster Accessories Safer by Covering Small Gaps and Holes

Published: content.blog_details_separatorJuly 28, 2026

Many hamster accessories contain small decorative holes or gaps that can become trapping hazards. Covering unnecessary openings with hamster-safe materials before use is a simple way to make accessories safer and reduce the risk of injury.

Why Cover Small Holes and Gaps?

Hamsters are naturally curious and will often investigate small openings with their nose, teeth or paws. If a hole isn't intended to be an entrance but is large enough to attract your hamster's attention, it could become a trapping hazard.

Before adding any accessory to your enclosure, check for decorative holes, narrow gaps or small openings that your hamster could attempt to squeeze through.

Accessories to Check

Common examples include:

Ceramic teapot spouts
Decorative windows
Coconut hides with drilled holes
Plant pots with drainage holes
Tealight holders
Mug and teacup handles
Bendy bridges
Decorative ornaments

Even accessories marketed specifically for hamsters should be checked before use. If an opening looks too small to be a safe entrance, it's best to cover it before use.

Drainage holes should be blocked.

Safe Materials for Covering Holes and Gaps

Suitable materials include:

Paper bedding
Sphagnum moss
Cork
Plain cardboard

These can be secured using a small amount of non-toxic PVA glue. Always allow the glue to dry completely before returning the accessory to your hamster's enclosure.

Making Bendy Bridges Safer

The gaps between bendy bridge slats can trap tiny feet, legs and nails, causing injury.

Filling these gaps with paper bedding or sphagnum moss helps prevent injuries while maintaining the bridge's natural appearance.

Check Your Modifications

Hamsters love to chew, so inspect modified accessories regularly.

Look for:

Loose coverings
New gaps
Chewing damage
Loose glue joints

Repair any damage before placing the accessory back into the enclosure.

When Not to Modify an Accessory

Not every accessory can be made safe.

If an item has multiple trapping hazards, unsafe materials or sharp edges, it's usually safer to replace it with an accessory designed specifically for hamsters rather than trying to modify it.

Frequently Asked Questions

Why should I cover small holes in hamster accessories?

Small decorative holes and narrow gaps can become trapping hazards if your hamster tries to squeeze through them. Covering unnecessary openings helps reduce the risk of injury or entrapment.

What materials are safe for covering gaps?

Paper bedding, sphagnum moss, cork and plain cardboard are all suitable options. These can be secured with a small amount of non-toxic PVA glue, provided it is fully dry before the accessory is used.

Are bendy bridges safe for hamsters?

Yes, but it's recommended to fill the gaps between the wooden slats. This helps prevent tiny feet, legs or nails from becoming trapped while still allowing your hamster to climb and explore naturally.

Can I use household items as hamster hides?

Many household items can be used safely, but they should always be checked for narrow openings, decorative holes, sharp edges and unsafe materials before being placed in your hamster's enclosure.

Do I need to inspect modified accessories?

Yes. Hamsters may chew or pull at covered areas over time. Check modified accessories regularly for loose coverings, chewing damage or new gaps, and repair them before returning the accessory to the enclosure.
