Yes, wet food offers many benefits for your cat. Cats naturally drink very little, since they are used to getting their water from the food they eat.
Wet cat food is generally made up of about 75% moisture, compared to around 10% for kibble, which helps complete their daily hydration and support urinary health.
This does not mean dry cat food should be avoided, but combining both formats can be very beneficial for your cat's health. The key is to always keep fresh water available for your cat.
