[10Minutes]

I don't think hamsters really overeat, I'd personally feel safer if I can see a little extra food lying around in my hamster's cage at all times. Hopefully others can comment on the proper portion for the pellets.

I couldn't see mine drinking water at first, so I would hold the bottle to my hamster's mouth and feed her water every night. She would drink, but she didn't seem exceptionally thirsty. I would keep offering it to her until I was sure she didn't want anymore. You could try that if you are concerned, then you can be sure she at least gets a little bit of water every day.

It was a long time before I could actually see her drinking from the bottle itself, but now it's a common sight. Maybe she was just shy and didn't want to let me see her drinking at the beginning.

I also bought a second bottle, so now I don't even get concerned because I know she has permanent access to both bottles at all times, in case one of them gets stuck. I always test both bottles after changing the water to ensure they are both working anyway. Would highly recommend a second bottle as it gives me peace of mind, and I start to worry when I know she's only left with one working bottle.

Some people do recommend bowls, you may see if it works for you. My hamster is very hyper at certain hours and kicks her bottles over a lot regardless of where I position them (this is exactly why having a spare makes me feel better because she kicks over a bottle or clogs it up about twice a week on average), so a bowl may not work for mine because it may probably be chockful of substrate within ten minutes of her wild burrowing and running.

P/s: Of course I fix her bottle mishaps within the day, it's just that if she kicks over a bottle while I'm at work, she'd have to wait till I got home. I'd hate to think of her going thirsty during that time. So far, she has never succeeded in putting both bottles out of commission at the same time and there's always one that's still working.
