Here's why:
* Toxic: Sellotape can contain chemicals that are toxic to gerbils. If they chew on it, they could get sick.
* Choking hazard: Small pieces of sellotape can break off and become choking hazards for gerbils.
* Not durable: Sellotape is not durable enough for gerbils and will likely break apart quickly, leaving loose pieces that are dangerous for them.
Instead of sellotape, consider using these safe alternatives:
* Glue sticks: These are non-toxic and safer for gerbils.
* Fabric glue: This is also non-toxic and can be used to securely attach fabric to toys.
* Safety pins: These can be used to attach toys to other objects or to secure them to the cage.
* Zip ties: These can be used to create sturdy connections for toys.
Always supervise your gerbils when they are playing with toys and ensure they are safe.
