Don't know about spiny mouse.
Our newsletter often refer to the Gerbils and how we should not kill them but rather discourage them to come into our gardens, especially when you have cats or dogs.
Our cat once caught a gerbil. I think he planned to eat it in the cupboard because that's where I found it ... alive and well.
In the last few weeks the dogs have dug up my entire bed of Agapanthus. They're not going to stop until they find and kill the poor thing.
Someone suggested that I find the start or end point of the tunnel, stick a hosepipe in and drown it. It seems cruel. I also don't want to use poison because my dogs and cats may eat it.
Burrows:
Gerbils make homes under the ground called burrows. Just like almost any other rodent there are rooms for sleeping and eating. The entrance to the burrow is round and is made a certain way so wind can't get in. Sometimes gerbils will build their burrows right next to each other and form a colony. Since gerbils are most active during the night they mostly stay in their burrow eating and sleeping.
