🤝 How to Bond Two Guinea Pigs

Introducing a new friend the right way, on neutral ground, so the pair settles into a happy little herd.

Guinea pigs are social but particular, and a good introduction sets up a lifelong friendship. Rushed on another pig's home turf it can go badly, so do it on neutral ground and take your time.

Step by step

• Neutral territory. Introduce them somewhere neither pig owns, like a clean playpen or the bathroom floor, with a couple of hides and piles of veg to share.
• Expect a pecking order. Rumblestrutting, mounting, chasing and teeth chattering are normal as they decide who is boss. Let them work it out.
• Step in only for blood. If a real fight draws blood, separate them with a towel (not bare hands) and try again later.
• Reset the cage. Before they move in together, deep-clean and rearrange it so it smells like neither pig's alone.

Good matches

Two sows, a neutered boar with sows, or two boars given lots of space. A calmer temperament pairs well with a bolder one. A bonded pair from a rescue skips all of this.
