We always recomend no. An in england this has become general advice because
- Buns are much bigger than piggies, if they were to kick out, they may accidentally hit the piggy and this could actually kill the piggy.
- Guinea pigs are nautrally very vocal, and buns cant understand their language, so thw pig and bun cant understand eachother.
-buns carry bacteria that although cannot harm them, can be deadly to guinea pigs.
- buns and piggies need a completly different diets.
These are most of the reasons they should not live together.
