Is he still a baby?

[GuineaNewbie]

I had recently put in a form to adopt a 3 month old male and a 7 month old guinea pig. But until now, I had never thought that they are still young. Would I need to baby-proof my cage? Or make the grid openings smaller?

Yes, you should baby proof the cage. Most pigs should be in a baby-proofed cage until roughly 6 months, but it depends more on size than age.

Good luck with your new pigs!
