Food that all the cats will like

We recently switched from dry food to canned Friskies due to one of the cats developing diabetes. 2 of the cats, including the diabetic cat love the wet food and eat it up. The other one doesn't really care for it. Any recommendations on what I can do to find something they will all enjoy that won't break the bank. I tried feeding just her the dry food but that's almost impossible with the other 2 around.

 

Have you tried Fancy Feast Salmon Feast classic?

Another one is Fancy Feast Chopped Grill classic?

And perhaps something low carb and dry as a treat?
Worked for me.

 

Some people have success with sprinkling a little bit of Fortiflora (a powdered, flavoured probiotic) on top of wet food. You can buy it online.

 

Have you tried crushing some of the dry and putting it on top of the wet? If it works, gradually decrease the amount of dry
