Why it might be considered weird:
* Human-like: Jeffrey is a very common human name. Giving a pet a human name can feel odd to some people.
* Formal: The name Jeffrey is associated with a certain formality. Some people think it's too formal for a small, fuzzy creature.
Why it might not be considered weird:
* Personal preference: Ultimately, it's up to the owner to choose a name they like! If you like the name Jeffrey for your guinea pig, there's no reason you shouldn't use it.
* Uniqueness: Choosing a human name might make your guinea pig stand out from the crowd.
* Fits the personality: Maybe your guinea pig has a particularly regal or sophisticated personality, and Jeffrey fits that vibe.
Ultimately, the "weirdness" of a name is in the eye of the beholder. What matters most is that you choose a name you love for your pet.
