You can never be too old to have guinea pigs. However, you can certainly be too YOUNG. Guinea Pigs are an investment of time and money. They can live for 8 years or longer. You need to think if you are able to really commit to their care for that long. If the guinea pigs are yours, you need to make sure you have the money to care for them, buy supplies, and the vet bills. Again, where will you be in 8 years? Will you still be in a position to care for them?

That being said, I've been an adult now for decades and I have 6 guinea pigs...I am their sole provider even though there are other family members in the household, I am the one providing 99.9% of the care. Since nobody helps out, I spend hours in the course of the week caring for them...shopping for veggies, preparing meals, cleaning the cage, washing and drying the fleece, giving them floor time and lap time. I love them so I do what is necessary to make sure they are happy and healthy.
