It's good to see more people taking an interest in what they feed their cats
Applaws - the kitten version - is a great food to give them, and as it's a
complete food there's no need to feed anything else.
However, as you know cats like variety. Other great
complete wet foods are: HiLife pouches, Bozita, Porta21... there are some others too but I can't think of them - I'm sure someone will come along soon and add to the list!
The adult Applaws versions are all
complementary, which means that it doesn't contain all the nutrients a cat needs. Basically it's meant to be fed as a treat, once in a while.
Oh, and if you're feeding dry food you will be fine to cut that out and just feed wet - in fact this will be better for your cats, and probably work out cheaper for you.
Hope that helps
