It's definitely unusual for cats to noticeably drink a lot of water, since they usually don't drink much at all - this can be a sign of many different illnesses, including liver or kidney disease, diabetes, or a thyroid problem. If you feel that Lucky's water intake has increased lately and is more than normal, I would recommend taking him to the vet for an exam as soon as you are able to. Your vet can do blood work and a urinalysis to help determine if anything is wrong, and get him started on appropriate treatment if any problems are found.

I would guess that this is just a personality quirk - some cats like to play with and drink more water than others. If he had kidney disease he probably would have other signs like a poor appetite and weight gain. You could always talk to your veterinarian about screening lab work if you are concerned.
