Have you checked the bottle is working ok & measured how much she actually drinks? It maybe less than you think.
Sometimes it can be hard to judge just how much they drink, while ingesting too much water from chewing the bottle is bad for them drinking too much is a different matter & if she is actually drinking a lot it could be a sign that something is wrong, possibly a UTI or kidney problem.
I saw your other post about sleeping at night & while that may just be natural behaviour, most active at dawn & dusk if she is less active then that can also be a sign that something's not right.
