Can Guinea Pigs Drink Tea? (Risks, Facts & More)

We love a hot cup of tea during the cold months when we snuggle up with the cup and a nice movie. Tea does not contain just herbal aromas, but fruit as well, which makes it even better for some of us. However, it is a risky beverage for the guinea pigs.

No, guinea pigs cannot drink tea. The main reason for this is that some types of tea contain caffeine, and this ingredient is not good for guinea pigs. Some types have artificial sweeteners or even artificial colors, which obviously are bad for anyone, including guinea pigs.

Can Tea Be Bad for Guinea Pigs

If there is excess theobromine, which comes from drinking tea, in the guinea pig’s system, it will have an effect of a strong stimulant. It will act as a diuretic and also as a vasodilator. It will widen the blood vessels, and this is bad because it might cause fatal bleeding in certain organs.

Too much theobromine can cause diarrhea and nausea. The guinea pig will feel ill and it wouldn’t be able to tell you. Notice any signs it shows, like strange movements, skipping, or upset sounds.

Tea lacks many nutrients that are good for the guinea pig. For example, it has no good vitamins. It lacks vitamin A which acts as an antioxidant for the whole immune system and all organs. Also, it lacks vitamin C that protects the guinea pigs from the scurvy disease.
