There are water bowls you can buy for crates that they cant tip over as it screws to the crate.!
If shes going in there to sleep them she really doesnt need alot of toys maybe just a little teddy or something like that.
Also of a night time you may want to take food and water out of her cage as she will be eating and drinking constantly and then needing the toilet.
We dont leave the light or radio on at night if we pop out we do but at bed time we leave the room dark with a blanket covering the cage.
All i would put in of a night would be bedding and maybe a little teddy.!
I dont no what other think about water and food in crate at night time but i have never put food or water in with mine at bed time
