Here's a breakdown:
* They can squeeze: Guinea pigs can fit through surprisingly small gaps, especially when motivated (like finding tasty treats!). Their ribcage is flexible and they can flatten their bodies somewhat.
* Size limitations: They are not as adept at squeezing as smaller rodents like mice or hamsters. Their size makes it harder for them to fit through narrow spaces, and there's a higher risk of getting stuck or injured.
* Safety: It's important to keep guinea pigs in a safe environment with no small spaces they could get trapped in. This includes making sure their cage and play areas have no holes or gaps they can fit through.
In summary, while guinea pigs can squeeze into surprisingly small spaces, it's not always advisable. It's best to keep them in a secure environment with no tight spots to avoid potential injury or distress.
