Yes, check the litterbox tag for heaps of advice. Kittens always try to eat the litter, make sure it’s not clumping and it may help to try a few different litters until you find one she likes (not strong-smelling and feels nice). Can she actually get in her litter box easily? An aluminium tray might be best while she’s still tiny. What’s more, I’d treat every area where she’s ‘been’ with a good enzyme cleaner and then put another litter/aluminium tray on top for her, for now. Kittens are like little kids, they forget to go and then get caught short, she might not make it to her tray in time or she might be too busy playing to want to make the trip! You can also try a product called Kitten Attract (it’s pricey so you can sprinkle some over her ordinary litter). Cats also feel vulnerable while toileting so her litter box/es should be somewhere quiet, calm, out of the house traffic and private (ie why she likes the under the bed, couch, etc). They can feel specially vulnerable in a multi-cat household. Best of luck!
