Dry food is harmful and can lead to diabetes, kidney disease, and shorter life span. You need to feed protein-rich, grain-free wet food.

The reason I asked: I have three cats and they all greet me when I come home from work and in the morning when I get up! Well, I give them wet food on schedule - 3 oz per cat in the morning and 3 oz per cat at night, so there is never any leftover. That guarantees that they greet me!

Since you are feeding dry food, your cat does not greet you - your cat has 24/7 access to food, probably.

So for both of these reasons - to bond with your cat better and to improve the cat's health and longevity prospects, switch to wet food. It is entirely possible - one of my cats (they all were fosters originally) ate only junk dry food because his previous owner thought that it was impossible to change the cat's habits. The volunteers at the cat rescue agency explained to me that the junk dry food was like feeding pringles to adults every day.

So... eventually he started eating high quality wet food (as he had no other options)... and lost 8 pounds and is now normal weight (he arrived weighing 20 lbs).
