How to Introduce Gerbils to Each Other

Gerbils are very social animals and should typically be kept in pairs or threes. It’s very common for a gerbil to end up alone through declanning or bereavement and if this happens you may want to try a new pairing so that your gerbil has someone to cuddle, groom and play with.

• Male gerbils accept cage mates fairly easily. It is easiest to introduce a young pup but another adult male may be possible.
• Female gerbils are the hardest to introduce to other gerbils. If you have a single older female try introducing a very young pup or a companion male via the split cage method.
• Don’t try to keep more than two adult females together – they will likely fight.
• Don’t try to keep more than four adult males together.
• Don’t try to introduce single gerbils to established clans.
• Do use the split cage method – it is the safest, fastest and most effective way to get gerbils used to each others scent.

Gerbils can be a bit trickier to introduce than other rodents. They are very territorial and need time to adjust to the presence and scents of another cage mate. That’s why the split cage method is the most effective means of introduction.

How to do a Split Cage Introduction

1. Assemble your cage. A tank with a wire mesh divider works well. Ensure all sharp edges are removed or concealed so your gerbils cannot get hurt. Make sure your gerbils cannot fit through the gaps but can see and smell each other. A double layered divider may be useful for particularly territorial gerbils.
2. Fill the cage with clean bedding making sure each gerbil has their own food, water and toys. Do not include anything that may hold scent as they may become territorial over this.
3. Place the gerbils one on each side. Swap your gerbils over three to four times a day so that they spend plenty of time in each side. Try to alternate sleeping arrangements so your gerbil sleeps in one side one night and the other side the next.
4. Watch their behaviour closely. If your gerbils begin to sleep in each others nests, sleep next to each other against the divider and groom each other, you’re ready to try an introduction.
5. Remove the divider and observe. There may be some grooming and scuffling but as long as they don’t get into a ball fight you should let them sort it out. If you seen signs of aggression, split them up immediately and return the divider. Watch the gerbils for several hours after a successful introduction as they may still fight later on!
6. Enjoy your happy new gerbil pair and the satisfaction of being a gerbil matchmaker!
