Iams/pets at home wet food?

Is this a good enough diet for 2 ragdoll kittens, they will be 13 weeks old when I get them.

The plan is:
Iams kitten dry food free feed
Iams kitten wet food 1 pouch each per day
Pets at home kitten wet food 1 pouch each per day

Is this okay for them?

Is there any supplements I should add?
