Why do my Guinea pigs drink water from only one water bottle. Hamster question is well….?
Don’t worry about you guinea pigs weight. I have 2 guinea pigs and the younger one is fatter. They might just prefer that water bottle. Maybe they don’t like something on the other one? I am 11 and my guinea pigs are about 2 and they are perfectly healthy. One tip. You could give them more celery but a big thing guinea pigs love well, mine anyway is lettuce! Also apples sometimes but they squeak whenever the fridge opens begging for it.
