Guinea Pig Cage Size (Recommended)

2 Piggies 2x4

3 piggies 2x5

4 piggies 2x6

However... the bigger the cage, the happier the piggies. 

What I suggest..

2 piggies 2x5 - 2x8 

2-3 piggies 3x4 - 3x5

3 piggies 2x7 - 2x10 

3-4 piggies 3x5 - 3x6

4-5 piggies 3x7-3x10

I personally give my piggies some floortime  everyday and they love it.

*Male pigs require a bigger cage compared to female pigs because they're more territorial.*
