Regarding water ... I mix the minimum (in cool weather) / more than the minimum amount (in hot weather) with my cat's dry (species specific) food, every meal. I also give Coconut oil when they show signs of illness (many times it corrects the problem, but there have been times of injury when it didn't & I took them to the vet). I also use C.O. reg. to prevent or move hairballs, as it's more effective than any other remedy I've tried, & mine LOVE it (except 1 that gets it put on his paw to lick off)! It works *great* for so many things, & they don't want to settle down at night until they've had their C.O.! I've also read that Coconut *water* is very useful for human UTIs.... Just thought I'd share.
