Hi - my mom has mentioned to me that Simba, the cat who used to live with me but now lives with my folks, has been drinking a lot more water lately than he used to. However, he still eats plenty, and is very playful and energetic, despite being 12 years old as of next month. Is the increased water-drinking something to be concerned about, or, as long as he's playful and active (and eats well), is everything fine?
Thanks!
Thanks!
