I'm very sorry to have to tell you this, but...when a cat drinks too much water, it is usually a sign of terminal illness, like kidney disease or leukemia. It's a very bad sign. You need to get the cat to the vet immediately, because if he is seriously ill, you will need to begin treatment/medication as soon as possible. The sooner you begin treatment, the longer he will live.
the cat could be sipping the water or washing its hands
Your cat is trying to get your attention. You also might want to take him to the vet if he isn't eating , drinking water, or exercising as much as usual.
Cats dont usually gag after drinking water. If your cat does then i strongly recommend visiting the vet, as it may have something stuck in its thoat that gets disturbed when drinking water. You can wait for a few days and if the cat continues to gag then take it to the vet. Though i doubt it there also could be a problem with the water.
Drinking water creatively
I doubt it. A cat will only drink clean water out of a toilet bowl, so the likelihood of a cat becoming ill from drinking water is unlikely. A cat usually contracts urinary infections from not drinking enough water and the urine becomes too concentrated.
Keep the toilet closed and make sure the cat has fresh water available all the time.
at the age of 5 weeks
Stretching out as much as they can, finding cool tiles to sleep on, sleeping in the shade or even the bath, drinking lots of water and they also have sweat glands in their paws.
warm up a nipple and put warm milk or water in a bottle
Cats don't like water, that's why cat drinking fountains were made, so that cats can drink water, milk, or any beverage basically without getting wet. These fountains can be purchase on eBay and pet supply stores.
Your cat may drink the water simply because it can. Some cats like filtered water more than regular water, and some will only drink certain types. If the cat has fresh water in it's bowl, it is probably just drinking out of the glass because it can.
It depends. Is your child a cat?
