No, it doesn't!
In fact, canned food makes cats less thirsty. Because water is part of the food.
But don't think this is a waste of food money. Because what it really is turns out to be dehydration insurance.
Why is this so important?
Cats are fussy about their water supply because, in the wild, there were few water sources in the desert. Cats grew used to taking care of their water needs by eating fresh prey. So while giving cats access to fresh water is important, getting them to actually drink it can be difficult.
When we feed canned food we make sure they are getting the water they need, when they need it. And there's lots of other reasons to feed canned: high protein, low carb, and twice the taurine of dry foods.
