YES
Yes.
To clean a water bottle you have to put fine sand into the bottle and then pour water and put one of your fingers to plug the bottle and shake for a little while and pour the sand and water out then rinse. Make sure the sand is gone. If you don't wash the bottle at all it will get moldy. Another way is to get a very small brush, stick it inside the bottle and scrub.
it is okay for any hamster to drink out of a hamster bottle as long as you clean the bottle.(you should clean it everyday)
The hamsters water bottle must be cleaned everyday. It is okay if you do it every second or third day sometimes.
for hamsters and rodents u always leave a dish of food in there cage along with watter and clean bedding so they can just help them selfs
Hamsters lick their paws and fur; they clean themselves.
I clean out my hamsters cage twice a week.
Dwarf hamsters clean themselves. I own one and watch him clean himself all the time. Dwarf hamsters clean themselves by pulling both paws from the back of their neck forward.
