I wouldn't agree with the 700-900g for females, that does sound a bit low. My 2 girls are both above 1kg and are not fat at all.
Very true - my 18month old girl is nearly 1300g while one of my other girls who is around 7momnths old is over 1000g rolleyes - even my smallest sow (who is coming up to 2yrs old) is over 1000g - and she feels very dainty and petit when you pick her up (i.e no body fat whatsoever)
Best thing you can do is weigh both pigs weekly - weight gain the their age is perfectly normalAny continuous weight loss and you should seek veterinary advice as it's often the first sign of illness...
Yes, my 2 girls vary(mostly because of the rubbish scales!) between about 1.1kg-1.5kg and they are not at all fat.
Healthy weights for healthy girls
I'm sure i read somewhere that a healthy weight range for an adult guinea pig is anywhere from 900g to 1800g - some guinea pigs carry weight better than others my 7month old texel girl looks and feels way chunkier/bigger than my 2yr old aby sow and both weigh more or less the same![]()
