If he is still alive after 7 months this probably means that he is just drinking when you are not around. Maybe for some reason feels insecure to do this when there are humans around. If there is actually no water missing from his water bottle then you have a concern and should talk to a vet.
Your guinea pig will drink it's water
A guinea pig water feeder or a water bowl.
Guinea pigs should drink fresh, clean, and preferably filtered water. Tap water that is free from contaminants like chlorine or heavy metals is suitable for them. It's important to provide a water source that is changed regularly to ensure it stays clean and fresh for the guinea pigs to drink.
you just put in the food and water. Your guinea pig will eat and drink until it is full.
You should. They need to drink, you know.
Because They Are Thristy -_-
No fish drink water. They absorb it through osmosis in their gills
water. they can only drink water. (trust me I have two, and by the way, Guinea pigs is two words.)
Does your Guinea pig like peanut butter ? (They generally do) rub peanut butter on the drink bottle outlet and eventually after you have done this many times it should eventually learn that water is also coming out, let it get a bit thirsty as well
they should eat the normal guinea pig food and drink from the water bottle.
It may have a soar throat. And bottom line, they drink lots of water.
ONLY guinea pig milk. Their mom will feed them her milk and then teach them to eat solid food.
