Guinea Pig Weight

[C.Courtney0310]

Hi everyone I just got my guinea pigs a little over a week ago from PetCo and was not told the age of them. They seem very healthy and eat/drink enough, but when I weighed them they were about 330gs. Does anyone know if theyre underweight of just young? Please help I'm scared if they will die Heres some pictures of them for reference:

They're probably just young. Make sure you weigh them weekly - they should gain some every week. Also feel their heft as well. I'll link in the guide below.

They’re gorgeous. They’re probably still babies in which they are good weights. Weigh them weekly and they should gain weight

Hi abd welcome!

They just look very young to me. Babies can weigh anything from 40-120g when born, and that difference will carry through and even get larger as they go through life. As long as they are eating well, are lively and active, please concentrate on providing a good general diet. Your aim is long term health and as long a life as you can; with the help of a good diet, they will realise their optimal genetically determined size and weight as adults. They still have a year to get there in their own way.

This guide answers all questions around weight, including how you can work out whether your piggies are good weight for their size at any age (which changes as they go through life) to monitoring any illness related weight changes. The 'heft' or BMI helps you establish the general ball park your piggy is playing in. The weekly or in the case of an illness daily weight changes help you to know when you need to see a vet and to monitor the food intake and what feeding support you need to provide during illness and recovery.
You will find the information in the guide not just very helpful but also very interesting!
Weight - Monitoring and Management

Here is our diet guide, which looks at all food groups in detail but also at the role they play in an overall diet. We have kept it as practical and precise to make things easy for newbies. It does contain a picture of a sample veg diet.

Both guides are part of our much more comprehensive new owners information collection, which you will hopefully find very useful. Unlike a book, we can update and extend our information at need. The guides will help you to learn what is normal and what, how you best care for your piggies, understand their behaviour and make friends with them with a spot of piggy whispering (and also use it to solve interactive problems).
