How old are guinea pigs in human years? Guinea pig age chart

Unlike humans, rodents undergo non-linear development during their growth process. Specifically, they have an accelerated childhood phase, during which their aging process is considerably faster than a human's. However, as rodents mature into adulthood, their aging rate slows down. On average, guinea pigs live anywhere from 5 to 7 years.

Below, you can see the guinea pig age chart that our tool is based on:

How do I take care of an aging guinea pig?

As your precious guinea pig ages, it is essential to put extra effort into making sure your furry friend has the care it needs. Some of the steps you can take to make your guinea pig's life more comfortable are:

  • Consult with your veterinarian regarding vitamin C levels in the diet. Since older guinea pigs are more prone to developing arthritis, vitamin C can assist in reducing inflammation. Although note that excess vitamin C intake may lead to kidney and bladder stones.
  • Try to weigh your guinea pig frequently. Older guinea pigs are more likely to develop various health issues, and rapid weight loss could be one of the indicators that you may need to visit your local veterinarian.
  • Ensure your guinea pig is eating and drinking appropriate amounts. You can do so by portioning your guinea pig's pellets and water in a measuring cup and marking it at the beginning of the day. Then, at the end of the day, use the same cup to observe how much water and pellets your guinea pig has consumed. If your fluffy friend stopped consuming food and water, it's time to visit the veterinarian.
  • Try to be observant of your guinea pig's eyes. If you notice your guinea pig's eyes as cloudy, white, or opaque, it may indicate cataracts.
  • Ensure that bedding for your guinea pig is soft and comfortable; this helps reduce pressure on limbs.
  • You may also need to rearrange your guinea pig's cage to avoid your guinea pig getting entangled in anything due to joint problems and an inactive lifestyle at an older age.
