It’s not usually necessary to take a guinea pig’s temperature. As long as the animal is kept roughly in conditions between sixteen and twenty-four degrees celsius then they should be okay. In the UK, anything below ten degrees celsius and you might want to bring your guinea pigs into a nice, warm, quiet spot inside, away from the noise of the house and far from any other pets you may have.
Owners rarely need to take their pets' temperatures
Guinea pigs aren’t able to sweat like we are, so it’s a good idea to keep a close eye on your guinea pig over the summer months in order to make sure they don’t overheat. In the summer, if you don’t have an Eglu Go Guinea Pig Hutch where the guinea pigs can move in between their house and their run at will, then you’ll need to provide a shaded area for them to keep out of the sun, as they’re liable to overheat and get sunburn, or worse, heatstroke.
If you need to take your guinea pig’s temperature, you will unfortunately have to do so with a pet rectal thermometer. If you have to take the guinea pig’s temperature then you’ll likely have been told by your vet, so make sure you ask them for a demonstration. Guinea pigs have very small anuses, so you’ll need a special thermometer and to use lubrication. Your pet should be between 37.2-39.5 degrees celsius.
