We had 2 guinea pigs, both make and one died. He was like a baby so it was devastating. We recently got Millie, a 3 week old baby whom we adopted because her family couldn’t take care of her due to her unexpected birth. At this point, she should be with her mom, but her original owners couldn’t care for her. First off, I’m not sure if sje’s actually a girl. I know the difference but her private area is dark so I can’t see if she’s really female. Also, if she is, she will be receiving a female companion soon (one week). I’m just nervous she isn’t a girl and I’ve never cared for a 3 week old. I know they need alfalfa, dry veggies and pellets, but she doesn’t seem to be to interested in eating. I'm sure she just needs to get comfortable but how can I find out if she’s really a girl before putting her with a companion? I am not giving her a friend until I’m sure there's no risk of pregnancy.
Hi and welcome
Please use our sexing guide to look at the areas that are less obvious but much more gender divisive. If both areas come back with the same answer, then you can be 100% sure. We can have a look at your baby, but we may not be able to judge from the outside appearance and in any case, we always ask our members to do their own safety hands-on check, as we are doing with our own new arrivals.
Our Sexing Guide shows you exactly where to look and feel and what to look for with comparison pictures for babies and adults at various ages and stages of development.
Illustrated Sexing Guide
Guinea pigs switch from mainly drinking to mainly eating a normal adult diet during the second week of their lives but they nibble on hay on solids right from the start. By three weeks the weaning process (2-4 weeks) is in full swing and it is the age boar pups need to leave any sows; sometime even a little earlier if they are very well developed. So no need to panic.
And definitely no throwing the kitchen sink at your little baby! Any extra amounts are truly minute. Your baby is perfectly fine on a normal
grass hay based diet with 50g of preferably green veg and herbs and instead of the recommended 1 tablespoon of pellets, she can have two in order to cover any extras. That is absolutely all that is needed! No extra alfalfa hay or bowls full of pellets or dried veg!
The example of my little surprise baby Tegan (the one in my avatar picture on the left) should help you to stop panicking. She was on a normal adult diet all her life long, was never ill and died shortly before her 8th birthday last August in the company of her auntie and her two same aged playmates that I adopted for her to grow up with.
