Whenever there is a sudden change in behavior, Casters always recommend a visit or at least a call to the vet. The kitty could have a blockage or have another medical issue that's causing dehydration. The only way to tell what the health issue is (and there IS an issue) is to take the cat to the vet. Good luck. Hope the kitty gets better fast.
