Hi Juan,
Well if you ask how much water they drink at one go, it is difficult to say because cats are intermittent feeder and drinker just like humans.
Let put it in this way.
Every cat is different, and each one will drink different amounts depending on their lifestyle, health, and environmental factors. For example, a cat that lives inside a cool house may not drink quite as much as a very active cat who spends a lot of time outside. Your vet will be able to tell you roughly how much water your cat needs based on their diet, lifestyle, and physical health.
Bear in mind that a lot of your cat’s water intake might come from their food. Wet cat food already contains some water, so a cat who has a wet food diet won’t need to drink as much as a cat who only eats dry food. Dry food contains very little water, so they need to make up for it by drinking enough. Your cat should instinctively know that they need more water and should drink enough to make up for it – after all, they feel thirst just like we do.
There are plenty of other factors that will affect how much your cat drinks. Like us, they’ll drink more if it’s hot, or if they’ve been physically very active, so take these things into account.
Check out the guide below and find out roughly how much your cat should drink per day depending on their weight:
Kitten (up to 3 months) - 1.4kg - 70 ml
Kitten (6 months) - 2.7kg -150 ml
Medium cat - 4kg- 200 ml
Large cat - 6kg - 300 ml
If your cat is drinking lots of water and showing other signs of illness, they should be checked and diagnosed by a vet. In particular, excessive thirst in cats can be a symptom of:
Kidney disease
Diabetes mellitus
Hyperthyroidism
Urinary tract disease
If your cat is drinking excessively, and they don’t have any other unusual symptoms, try thinking about the cause. Is your house very warm? Are they only eating dry food? Has their drinking increased because it’s summer?
If you can clearly put your cat’s excessive drinking down to an environmental factor, it’s enough to keep an eye on their general health and behaviour. As long as your cat is healthy and happy, and they’re getting plenty of fresh water when they want it, they should be fine. You might want to make a note of it and ask your vet at their next check-up, just to put your mind at rest.
If your cat does appear to be unwell, book them in to see the vet as soon as possible. Remember to tell them that your cat has been drinking a lot, and note any other unusual symptoms. They will be able to diagnose your cat and find a possible treatment.
Other tips
If your cat is drinking a lot from unusual sources – such as dripping taps – make sure there’s nothing wrong with the water you give them to drink. Many cats will shy away from a water bowl that isn’t squeaky-clean, and like us, they much prefer fresh water.
If your cat has recently switched from wet food to dry food, they may experience increased thirst. Keep an eye on it, but bear in mind that cats who eat dry food do need to drink more.
Hope it will help you.
Thank you
Best regards.
