Even though it's a delicate problem in most cats, my cat has always been drinking acceptable amounts of water (usually 3/4 of her bowl per day, which is equivalent of ~300 mL, she is weighing 4.5kg ).
Because of the extreme heat wave of this summer, I've decided buy one of those water fountains. The problem is, she is absolutely crazy about the fountain and this new drinking technique. And most of the time, she drinks so much that some gurgling sounds can be heard when she climbs up/down to somewhere after drinking (and the occasional cat coughing from drinking too hastily).
She is now drinking at least 700mL of water per day which I'm worried about. Every other behaviour (eating, activity) of hers is completely normal. When I consulted my vet about the situation they simply said it's normal with the extreme heat wave.
Can extreme water drinking can possibly make my cat ill or cause some sort of problem with her overall health ?
