One of our pair of gerbils died this week. The other one seems to be well but I know they are social animals and so she will get lonely if we don't do something. They are/were only around 1, so the one that's left is likely to have a good bit of life ahead of her.
All the gerbils I have seen advertised are in pairs. Our tank is not big enough for 3 and I don't think it's so easy adding a pair to a single.
I am aware of the split cage method and would be up for doing that, but I have no idea where to get a single female gerbil from.
Any ideas anyone?
