Rats actually train pretty well, but don't expect perfection - they'll still pee sometimes just like that, from stress or during play. That's normal. But you can set up a main toilet if you understand their logic: rats really do pick corners themselves for doing their business, usually far from the nest and food bowl. If you notice where she goes most often, that's where you put the litter box. You can use a deep container with litter, wood shavings, or just paper - just not clumping litter, it's bad for their breathing.
The main thing people often miss: don't remove all the smell from the cage right after you set up the box. Leave a bit of used litter in the container - by the smell the rat will understand that's the toilet. If the box gets "redesigned" after cleaning, the rat might get confused. Also make sure the box is a comfortable size and height: if the edges are too high, she won't want to climb in.
The process will take 10-14 days max if you pick the spot right. If she stubbornly ignores the box though - check if maybe it's too close to the food or sleeping area. Rats are cleaner than they seem, you just gotta give them a proper choice.
A litter box with filler (or just a container) should be placed in the corner where the rat is already going to the bathroom - they usually pick one or two spots, and if you put the box there, she'll quickly get used to using it 😊 The main thing is to clean the litter box regularly and praise the little one when she uses it, that way she'll learn faster.
Rats don't always take to litter training perfectly, but there's a chance. The main thing is to understand that they naturally do their business in one or two corners of the cage, so that's where you need to put a container with litter or just a box. If you do it patiently and praise her every time she uses the litter box on her own, she'll get used to it in a couple of weeks.
Rats mark their territory with urine not just in the toilet, but also while moving around the cage - it's how they navigate their space. So even if you train them to use the main litter box, you won't be able to completely avoid puddles, and that's normal.
What actually works: watch for a day or two to see where exactly the rat poops most often (usually in one corner), and put a litter box or a bowl with litter there. Rats instinctively go to one spot, so if it happens to match, she'll quickly figure out what that thing is for. But with peeing - that's trickier. They'll make little puddles wherever, especially if they're stressed or playing actively. This is just a quirk of their physiology, not a lack of training.
If you want to minimize the mess, the main thing is to change the litter in the box frequently so there's a fresh smell, and clean up the soiled corners of the cage so the rat doesn't create new toilets in other places. Over time she'll still prefer the main spot, just don't expect perfect cleanliness.
Don't forget to change the litter in the box regularly - if it gets dirty, your rat might just pick a new corner instead of using the box! The smell of fresh litter attracts her, but she might ignore stale litter and start marking nearby instead. One more thing: some rats actually prefer to pee where there's already a smell, so for the first day or two you can put a bit of used litter from their favorite corner into the box, so the scent gets familiar with the new spot.
Does she actually pick a spot for her toilet in the cage or does she just go randomly in all the corners? Because if there's at least some place she likes, then yeah, put the litter box there - rats pick up on the logic just fine. But if it's really gone downhill and there's mess everywhere, frequent cage cleaning might help to guide her with scent to the right spot, and then you can put the litter box there.

Yeah, she's picked out one corner. Thanks, I'll try putting a litter box there.
You won't be able to completely avoid marking scents throughout the cage - it's just their nature, how they navigate. But you can definitely set up a main toilet area. Watch which corners your rat uses most often to do her business - usually they pick one or two spots. Put a litter box or just a shallow container with litter there (even a regular rag or paper will work). Rats naturally prefer to relieve themselves in a specific place, so when the box appears where your rat's already gotten used to going, she'll start using it.
Just keep that litter box clean and gently move any accidents from other parts of the cage into it. Over time your rat will understand that's her toilet. Yeah, sometimes she'll pee from stress or right while she's running around the cage - that's normal and unavoidable. But she'll do most of her business in the box.
Don't put litter boxes everywhere "just in case" - that'll just confuse the animal. Rats really do pick one or two corners for their bathroom, and that's where you need to put the container. But here's the important thing: observe for at least a day or two first to see exactly where your rat prefers to go, before you set anything up. Otherwise you risk wasting time.
The folks above are right that rats mark their territory and you won't completely avoid puddles - that's just a fact, no arguing with it. But about perfect litter training: the difference is that if the litter box is in the corner the rat's already chosen, it'll use it for its main bathroom about 80-90% of the time. The rest - yeah, that's marking, and that's normal. You can put the old litter from the box into the new one - the rat will catch on faster that it's the right spot.
If your rat's aggressively resisting and going everywhere, check if there's stress or illness. A healthy rat litter trains without issues if you do it right.
