Age

What’s the best way to figure out how old your Guinea pigs are?

Once they reach adulthood there is no real way to be 100% sure.
You can of course work out a lot from their history (if you know this) but after that their nails will usually indicate if they are older, but not down to a specific age really.

Would you like to tell us what you already know about your pigs and we can try to help?

It's hard to determine once they are full-grown. A couple things to look at are shoulder-blades/hips and nails. Older pigs tend to lose muscle mass and they feel bonier and less 'padded' around the shoulders and hips. Most of my pigs have become noticeably less muscular around age 5 or so. So if you can feel their shoulder blades and pelvis, it is likely that they are older adults (maybe around 5 or more.) Pigs also get thicker/twisty nails as they get older, and they can even grow in weird corkscrew patterns. A pig with nails that grow straight and are not that thick is probably a younger pig... a pig with thick, twisty nails is probably older. Looking at the two I have now, Tomie is about 1.5 years and still has thinner, straight nails... Leela is 6+ and her nails are atrocious! LOL! If they still have little tiny sharp pointy nails they may be quite young and haven't had their nails cut... baby nails are sharp!

Yes they definitely have thin straight nails and feel muscular still…thanks for your help
