Thank you for rescuing her! Sorry about your kitty, that all sounds very stressful.
The set up looks pretty good, I would just be careful with the stuffed animal, and keep an eye on the blankets to make sure she doesn’t chew them, especially the stuffed animal.
If she does start chewing the blankets a lot, you can put down cardboard and fleece blankets to protect your floor. Fleece is safer if they accidentally ingest some.
I like the box with the hay, I would just remove the tape in case she chews that part. Most people provide hay in or near the litter box to encourage them to use the box (as most bunnies like to poop while they eat hay).
She also might appreciate a box with two entry holes cut out so she can use it as a hide-out.
Her markings look like my Bertha!
An inch of carrot a day might be a bit too much, but you can gauge from her poops. If she produces extra squishy ones, she’s prob getting too much carrot.
A good next veggie to introduce is romaine lettuce or carrot tops (the leafy green part). Dandelion greens are also very popular, nutritious, and well-tolerated.
