I have to say, it was really disheartening to read so many similar responses and nobody steering you in the right direction (no offense to anyone here - I was one of you for a long time).
Please take some time one evening and visit catinfo.org (articles written by an accredited veterinarian, not some random schmo).
First off - cats are obligate carnivores. Their natural prey is over 70% moisture (small mammals). They naturally have a VERY LOW thirst drive, because they get almost all the moisture they need from their food. If your cat is a “good drinker”, then that’s a sign your cat is not getting the moisture they need in their diet. It’s not a good thing. Cats shouldn’t be making trips to the water bowl/fountain multiple times a day. That’s their kidneys screaming for more moisture.
Cats do not do well with lack of moisture (i.e. dry food = full of carbs = BAD), nor should they have readily available food at all times. Healthy cats are not “chonky” or “tubby”, as cute/funny as that might seem. Cats should look like lean, mean hunting machines (with slight variability depending on breed, obv). Svelte, sleek, shiny-coated hunters. And healthy, happy cats will play, hunt, pounce, and get zoomies well into their teens.
Please please consider reading up on cat nutrition at the above link. Most vets only get a token (outdated!) course or two in vet school on nutrition and that’s it. I had to switch vets twice before I finally found a phenomenal vet who continually does research and encouraged me to buy good grain-free wet food and supplement with raw. She is a gem.
good luck <3
