Hi again. Those bottles and stands have a safety issue someone told me recently
. If you can find a Ferplast drinky 75ml bottle they are good - you can stick them to the side of the cage with velcro maybe. Or if you want to have a bottle stand, some people make them out of an old plastic bottle or something similar with the top cut off and a hole in the side. You can buy bottle stands but they can be a bit expensive. Can you order from Germany? Rodipet in Germany do very good hamster stuff and they have a good bottle stand that comes with a classic mouse sized bottle.
Substrate: I'd avoid any wood based ones like aspen and pine shavings, mainly because they are common ones to be allergic to and tend to be dusty. The paper bedding will be much less dusty than Carefresh as Carefresh isn't paper, it's some kind of processed wood pulp.
If you can order from Amazon uk then "Fitch" paper bedding is what I use and a lot of other people use on here. And I find it dust-free and certainly doesn't cause allergies - and it doesn't smell of anything. It sounds like paper or cardboard bedding will be best for you
We have some called Finacard as well which is shredded cardboard.
This is the link to the Fitch - it's quite a big bale and I don't know if they'd post to you. It's not that heavy and can be stored fairly easily indoors as you can squish it into different shapes to fit under things or in a wardrbobe eg

I'm sure the petlife one will be similar but I haven't tried it so not sure how soft it is. The Fitch is nice and soft.
It's lovely that you took on this little hammy. Keep coming on here - it's very friendly and there are people with all kinds of experience, and breeders and lots of good ideas!
As for hamster pee - using a potty litter tray helps as then there is less cleaning to do and you empty the potty every 4 or 5 days. Our hamster started using his straight away and the rest of the cage stays dry, so less big cage cleans to do - I only end up doing a full cage clean about every 3 months now, and even then it's a partial cage clean.
I have this one, which fits in their pee corner, but any dish will do. Chinchilla bathing sand is good to put in it and helps stop odour.

Ours likes to sit in it and have a little wash in the front half and pees in the back corner

Sorry - just seen you have a toilet already! You could try sand in it. Needs to be Chinchilla sand though and not 'dust'.
Shavings is pine wood (sometimes called sawdust).
