Guinea pigs are good at hiding extra weight, being genenrally chubby looking little things to start with. Unless you weigh your pets regularly you can't really check for changes in weight. However, weight loss or gain can be an indication of a health problem.
The weights of your guinea pigs will change slightly throughout the year, but dramatic weight loss means a trip to the vet.
Weight fluctuations can indicate health problems
Once you’ve established your guinea pigs’ base weights, carry out these checks:
- If your guinea pig weighs less than about forty or fifty grams less than the last weigh in, this can just be part of normal fluctuations.
- If your guinea pig weighs more than fifty grams less than the last weigh in, then weigh them each day and give them some more dry food just in case.
- If your guinea pig weighs around one hundred grams less than the last weigh in, then this is very serious, and implies there is something seriously wrong. If this has been happening over a long period, then it’s still cause for concern, and your pet will need to see a vet immediately.
Foods For Weight Gain
If your guinea pig hasn’t been well and needs a bit of TLC, feed them more dry food than usual, plus a little more hay, carrots and corn: these are good, dense foods for a recovering GP.
